I have an Excel workbook that calls a test DLL I wrote in C++. The path to DLL is hardcoded in VBA. The only files the DLL uses are stdlib and iostream.
On my machine it works. On several other office machines it works. However, on the remainder when i try to call the DLL through Excel I get error 48 — file not found.
My understanding is error 53 is the file is missing; error 48 is there are missing dependencies. I have used dependency walker and have not found any issues.
What I did discover, however, is that if I install Visual Studio on a machine there is a 90% chance that after the install the Excel file/DLL works perfectly. On the 10% that it does not work, I restart and re-run the Visual Studio install, selected ‘repair’, and after the installation finishes again the Excel/DLL combo works. So basically installing Visual Studio allows the DLL to be loaded by Excel. If i uninstall Visual Studio the DLL still works fine.
Obviously this means something is missing on those machines, but I have no idea what — I’ve tried separately installing all the pieces that show up under ‘programs’, such as most current .net framework, visual c++ re-distributables, etc… and it doesn’t work. The only thing that works is installing Visual Studio itself.
I’m not certain how to proceed since asking users to mount a 5gig ISO and install a developer environment isn’t really ideal.
Ah-ha, I found the issue. It turns out that it requires 2 DLL files — msvcr120.dll and msvc120.dll. I had these 2 files in my System32 folder, but not in my SysWOW64 folder. As soon as i populated that folder then the DLLs started working.
I found many threads on google with the ‘same’ problem but no answer, so if you run into the same issue I’d suggest using dependency walker and making sure the DLLs are in both system folders to be safe (although I suspect System32 is only needed for 64bit DLL, and SysWOW64 for 32bit DLLs).

Good evening,
I am having a recurring error anytime I attempt to use Solver:
Run-time error ’48’:
File not found: Solver32.dll
I have done an install repair, uninstalled and reinstalled office, and spoken to Microsoft support, but the problem persists. Any assistance would be much appreciated.
Thank you

If you search for solver32.dll is the file found? It should be in a specific folder, like
C:Program FilesMicrosoft OfficeOffice??LibrarySOLVER
IIRC, solver is an installation option, and so needs to be chosen at the time of installation…

Hi,
Based on your description, the SOLVER32.DLL file may missing or corrupted, first please refer to the folder of Bernie Deitrick provided and confirm if there are 2 files under that folder.
Then you can try to reload SOLVER feature in Excel, please follow these steps.
Open VBA Editor- go to Tools- References
Then select Browse- go to C:Program Files (x86)Microsoft OfficerootOffice16LibrarySOLVER-change File type to Microsoft Excel files(*.xlsm;*.xlam..)- select SOLVER.XLAM.
Now please restart Excel and confirm if it works now.

Thank you for the instructions. I have the two files in the SOLVER folder. I then went to the VBA editor and completed the steps you suggested there. I restarted excel, opened solver, clicked solve, and received the same error again:
Run-time error ’48’:
File not found: Solver32.dll
Are there additional steps that I can take to try to correct this error?
Thank you,
Chris

We are aware of an issue with Solver, caused by the initialization of Power Query and Power Pivot. We are working on a fix for this issue urgently. In the meantime, you might be able to get unblocked with
the following workaround:1)
Make sure Excel is not running2)
Start Excel3)
Open the “Blank workbook” template4)
Launch Solver (click the Solver button in the Data tab in the Ribbon)5)
‘Set Objective:’ will be the active cell by default6)
Set the range in ‘By Changing Variable Cells: to the same string as is in ‘Set Objective:’7)
Click the “Solve” button
Close the Solver Results dialog9)
Open any other worksheet or workbook (do not close empty workbook first)
Hope this helps!

A suggestion in another thread worked for me (I wasn’t able to paste the link directly)
Here’s the quoted text from user Trekdoor:
«For me worked this: I copied the solver32.dll into the office16 folder.
e.g. (for me):
C:Program Files (x86)Microsoft OfficeOffice16
I guess there is a bug in the solver32.xlam, referring to the wrong (or standard) folder for dll’s.
T.»
I hope this helps!

try removing Solver from the references in the VBA window.
- Click «Alt + F11» to view the VBA Editor
- Click Tools > References
- Uncheck «Solver» then close.
- Restart excel workbooks
- Repeat the previous steps but this time make sure to check «Solver»
- Restart and it should work.
If the above steps do not yield a good results, try to remove the solver from the «Excel add-ins», restart then add Excel back on then restart.
Good luck,

We usually see Asus products having Excel Solver issues. This is due to the bundled WPS Office. They have their own Solver plugin that clashes with Microsoft one. Uninstall that piece of bloatware and you should be able to click «Solver» under
«Data» ribbon in Excel.

MSDN Disc 2434.7-related Excel.dll issues happen during installation, when Excel.dll-related software is running, startup/shutdown, or during the Windows installation process. Keeping track of when and where your Excel.dll error occurs is a critical piece of information in troubleshooting the problem.
Excel.dll Problem Causes
Missing or corrupt Excel.dll files are common sources of Excel.dll errors. As an external file (Excel.dll), it makes MSDN Disc 2434.7 issues more likely.
Improper computer shutdowns or malware-infected Excel.dll files can cause issues with MSDN Disc 2434.7, leading to corrupt errors. When your Excel.dll file becomes corrupt, it cannot be loaded properly and will present an error message.
In rare occasions, Excel.dll errors with MSDN Disc 2434.7 are due to Windows registry faults. Invalid references prevent proper Excel.dll registering, creating problems with MSDN Disc 2434.7. These broken registry keys can be as a result of a missing DLL file, moved DLL file, or an leftover DLL file reference in your Windows registry from an unsuccessful software installation or uninstallation.
More specifically, these Excel.dll errors can be caused by:
- Corrupt or invalid Excel.dll registry entry.
- Excel.dll file corrupted from malware infection.
- Microsoft’s (or related) hardware has failed, corrupting Excel.dll.
- Different software install overwrote Excel.dll version needed.
- Excel.dll maliciously (or mistakenly) deleted by different rogue or valid program.
- Excel.dll maliciously (or mistakenly) uninstalled by different rogue or valid program.

DLL file not found after saving as newer version of Excel
We have a program made in excel from an external supplier to help us create internal programs by embedding it into a workbook. The program sent to us has been made as a .xls 97-03 spreadsheet and works fine on its own, when saving as a .xlsm file in 2013 it says it cannot find the third-party .dll file when the code is run.
Any suggestions to fix this?

Re: DLL file not found after saving as newer version of Excel
Hi Rory, due to it being a company program I can’t give too much.
The workbook references a .dll file and uses «Public Declare Sub NAME Lib «DLL File» (etc.» to communicate with the file. Opened as a .xls 97-03 file type works fine, when saved as an .xlsm 13 file it gives the run-time error 53 DLL File not found when trying to run the sub NAME.

Re: DLL file not found after saving as newer version of Excel
Not in that line of code but it is referenced later on before Calling that sub. This works fine when it is an .xls file. The file path is «C:Program Files (x86)Folder» and I’ve tried it with and without another «» after the folder name.

Re: DLL file not found after saving as newer version of Excel
I am trying to use Solver in 64-bit Excel 2010.
When I run Solver, it opens the solver window, states that it has results and then popups the following error message:
Run-time error ’53’
File not found: Solver32.dll
So, it would seem that the Solver32.dll cannot be loaded. It is however, available in the Solver Directory — i.e. C:Program FilesMicrosoft OfficeOffice14LibrarySOLVER contains SOLVER.XLAM and SOLVER32.dll
What have I tried so far…?
-
did a full Office 2010 Repair
-
this Microsoft forum suggested copying the Solver32.dll to C:WindowsSysWOW64 (which is where Windows 7 stores it’s 32-bit dlls).
-
this forum suggested installing the Solver add-in (.xlam and .dll) to ..AppData..MicrosoftAddIns
I have tried both of these and neither of them worked…
- Remove From My Forums
-
Question
-
Im using Excel 64-bit. Solver used to work fine in Excel 2007, but now it shows:Run time error:54. File not found: Solver32.dll when trying to run the Solver after dialog input.
Is solver uncompatible with 64-bit Excel?
All replies
-
Are you sure that the add-in was enabled? Check via Excel Options ->Add-Ins…
HTH,
Eric
-
Yes, the dialog boxes shows as usual. After I press «Solve» it runs, but does not show any result. Only the error message.

This article http://msdn.microsoft.com/en-us/library/ff837594.aspx says that there’s a 64 bit Solver included with 64 bit Excel, so your install may have deleted the Solver32.dll.
I’d check your add ins and see if you have the 64 bit version, disable the 32 bit, enable the 64 bit. Just to check, do a search and see if you still have Solver32.dll somewhere on the PC.Cheers,
Eric

Thanks, but does the 64-bit solver have another name, like «solver63.dll»?
I have 2 solver-files in «C:Program FilesMicrosoft OfficeOffice14LibrarySOLVER»
solver32.dll
solver.xlam
We have 3 computers with Excel 2010 64-bit. Fresh installed. So it cannot be only my install. It worked fine in Excel 2007.

Hi,
The reference file has the same name of SOLVER.XALM unregard of 64-bit or 32-bit. Please check this document:
Using the Solver VBA Functions
However, the reference file locates on different path.
If your computer is 64-bit and the Office is 64-bit, the file locates at:
C:Program FilesMicrosoft OfficeOffice14LibrarySOLVERSOLVER.XLAM
64-bit OS & 32-bit Office:
C:Program Files (x86)Microsoft OfficeOffice14LibrarySOLVERSOLVER.XLAM
You can try to add reference to SOLVER.XALM manually to see if it will fix the issue.

I checked now, and I only have one version of the file in
C:Program FilesMicrosoft OfficeOffice14LibrarySOLVERSOLVER.XLAM, so it must be the correct version. I tried to add a reference, but it did not help. -
Did you try to add a reference in VBA or did you check it as an active add-in in Excel?
-
I tried both
Same error.
This code fails on last line:
SolverOk SetCell:=»$M$6″, MaxMinVal:=3, ValueOf:=22, ByChange:=»$L$6:$L$7″, _
Engine:=1, EngineDesc:=»GRG Nonlinear»
SolverOk SetCell:=»$M$6″, MaxMinVal:=3, ValueOf:=22, ByChange:=»$L$6:$L$7″, _
Engine:=1, EngineDesc:=»GRG Nonlinear»
SolverSolve? Err.Description
File not found: Solver32.dll» -
OK, I don’t have the 64 bit version so I can’t check anything.
This article says you must have both the add-in enabled and the reference selected in the VB Editor:
http://msdn.microsoft.com/en-us/library/ff196600.aspx It shows you how to do it if you have what they expect are the ‘usual’ problems. Your error indicates to me that either you
haven’t done both, or that one of the methods (and probably the VBA reference) is still pointed to the old version. The only thing to do is to check that you’ve got the correct reference by surfing to the dll in the folder that Calvin pointed out above.Other than that, I think you’ve stumped everybody. Sorry.

Thanks Eric for your help
File not found: Solver32.dll»
Hi,
How about the issue on your side now? I guess that the Slover32.dll corrupted in your computer. Have you check if the file “Slover32.dll” is existed
under the subfolder of “C:Program FilesMicrosoft OfficeOffice14LibrarySOLVER”? As I delete the “Solver32.dll”, I got the same “File not fount: Solver.dll” error. See the illustration:So you can try to reinstall Excel (not whole Office) to see if the issue will be resolved.
I look forward to hearing of you soon.

Sorry to bother again
I tried to delete the solver32.* files, and did an Office 2010 repair using the built-in function in Office. The files were restored.
But the problem prevails…
-
I had the same problem, and it was caused by an add-in that somehow modified the working directory. Try the following:
1. Enable the VBA/Developer tab.
2. Go into COM Add-Ins under the Developer tab.
3. Uncheck all of the boxes.
4. Restart Excel.
Then plug in some values for Solver and see if it fixes your problem.

Wonder when will they fix it in an update.

Thank you so much! These very specific location directions helped me!
-
Thanks! You save me! It also worked to office 2016!

This one worked for me. I had Webex productivity tool in the COM ADD-Ins enabled. Once i disabled. The solver worked for me. Thanks a lot.

So basically, what we have here is yet more incompetence shown by Microsoft developers. They’re basically programming a
64 bit program to look in the 32 bit library (System32)!!! It would make more sense if 64 bit Excel looked in the SysWOW64 folder! But nope, we can’t have sensible programming when we’re buying from Microsoft. Unbelievable that they still
haven’t patched this either. Microsoft needs competition. Being a monopoly has caused them to be extremely sloppy. -
Thanks JoBne, your solution fixed it for me too!
But I make a symbolic link in command prompt.
Same result.mklink “C:WindowsSysWOW64solver32.dll“ “C:Program Files (x86)Microsoft OfficerootOffice16LibrarySOLVERSOLVER32.DLL”

Thank you very much, JoBne and special thanks to Raisinasm, I was able to fix this problem on my very own (and in general I’m always drawing the «blond joker», since I am really far away from being an IT Pro). Now I am extremly
proud on myself, though it’s just because of Raisinasm’s perfect, detailed description. Thanx again, you made my day.Tax

Thank you JoBne, after I tried all other solutions, yours finally fixed the problem. Thank you very much
