Getting "mfc140u.dll is either not designed..." error message

[Urban L]

Has anyone else gotten the
 

error message?

This came up today for the first time.  I've uninstalled Lightroom Classic and re-installed it twice.

I ran Microsoft's SFC utility, but that came out clean.
I read on one post this type of error may be due to a recent Window's update.  

Any ideas?

Thanks!

Just using google on that. And as you stated perhaps an Windows update that went south.

for example: https://appuals.com/bad-image-is-either-not-designed-to-run-on-windows-or-it-contains-an-error/

or perhaps: https://answers.microsoft.com/en-us/windows/forum/all/msvcp110dll-file-not-working-need-help/aa09ed8...

I finally got it resolved by replacing the version of mfc140u.dll I had with a version that I downloaded from www.sts-tutorial.com.

I did it with a bit of trepidation with fear that I was also downloading some malware along with it.  If the Internet suddenly goes down in the next week, it might have been me.

I have the same issue after upgrading to Lightroom Classic 9.2. Reverting back to 9.1 was OK.  In your case, have you had further problems after replacing mfc140u.dll ? I'm a little reluctant to do it for fear of creating even more problems after.

I haven't had any trouble so far.

For the folks needing to replace an MFC DLL, I would recommend downloading the install package directly from Microsoft.

I am having the same error. I have tried both of the methods here with no luck. I did have snags on my windows updates and had to force them but no luck after that. If anyone has any other methods that may fix this issue I would love to hear it.

This worked for me, downloading both available files.  Thank you!

Lightroom Classic & Lightroom won't open mfc140.dil was not found?

I updated the app and now it wont open on my computer. I can use it if I am on an online browser, but not as an app on my computer. I get a little tab that pops up and says, " The code execution cannot proceed beacause mfc140u.dil was not found. Reinstalling the program may fix this program." I have tried to reinstall the app but the same thing happens. Is this a fault in the app or my computer?

Hi everyone, just fixed my issue with mfc140.dil. First load this page.

mfc140u.dll : Free .DLL download. - DLLme.com

Then go to windows Icon and type in search bar System Information > Click on Service info and find what bit your laptop is running on.

Select your system type then click download. Once complete open the file to see it's now downloaded.

Now click on My PC > Hardrive > Windows file > locate System 32 file

Now drag and drop your new MFC140 file into the System 32 file, if you get replace file, click on replace file. Once completed LrC & Lr opened up. Hope this helps everyone.

Downloading executables from some random web site is extremely risky. You never know what's lurking inside of that file.

This fixed my problem. Thank you!
