CARDFILE_32.EXE stopped working after today's Windows Update

Question

Yes, I still use this app and it has always worked until today:

I have unsuccessfully tried various options in Compatibility Mode as well as disabling Exploit protection for this app.

Is there any way to get around this? Thanks.

Answer 1

I had a similar issue after the application of update KB5086672 on my Windows 11 install running 25H2.

After running the dependency checker tool (available on GitHub https://github.com/lucasg/Dependencies?tab=readme-ov-file) on the .dll file pointed in the error message, I found out that the issue was coming from a modification of the crtdll.dll file present in C:\Windows\SysWow64 that didn't expose some symbols that were used by my legacy .dll file (there seems to have been a jump in version from 4.0.1183.1 to 10.0.26100.8115 for this .dll file.

Strangely enough, other Windows OS version (Windows Server 2019, 2022 and 2025) do not have this file updated up to now ... so I could take the crtdll.dll from a another machine working and copy it locally in the installation folder of the application running the .dll file that was identified in the error message. That is a working temporary fix for me.

Hopefully, this is an involuntary breaking of support of legacy application (I read on other forums reporting this issue, i.e. https://sourceforge.net/p/mingw-w64/bugs/1021/, that this is breaking 30 years plus of stability for this particular .dll) ...

I hope that helps.

The issue is caused by the fact that the Windows 11 update build 26200.8116 replaced the system component crtdll.dll with a copy of msvcrt40.dll, which is a different incompatible c runtime library, in which the software cannot find the required exported functions

Answer 3

The error indicated on the dialog in your screenshot indicates an internal error in that software installation, that is not a Windows dll that is listed.

Completely uninstall that Card File software, then restart (not shut down) your PC and download and install the latest available version of the software, then run the software in Windows 7 compatibility mode to test if it then runs successfully.

If that does not resolve the problem, open the Settings app, then go to Windows Update - Installed Updates, what is the KB number of the update that was installed that may have caused the problem.

Answer 4

The error indicates that this very old 32‑bit application is now calling a procedure entry point that no longer exists in the Windows DLLs after the latest update, so the executable cannot be loaded. Compatibility Mode and Exploit protection changes do not fix missing or changed DLL exports, so they will not resolve this.

The only supported options are:

1. Try the Program Compatibility Troubleshooter
   1. Select Start > Settings > System > Troubleshoot > Other troubleshooters.
   2. Run Program Compatibility Troubleshooter and point it at CARDFILE_32.EXE.
   3. Let it test different settings (older Windows versions, reduced color, etc.) and apply the suggested fix if it finds one.
2. Check for an updated version of the app
   • If this app came from a third party, check the publisher’s site for a newer build that supports current Windows versions. Search for terms like “Windows 11 compatibility”.
3. If no update exists, use an older Windows environment
   • If the troubleshooter and publisher do not provide a fix, the remaining practical workaround is to run this legacy program inside an older Windows version (for example, a Windows 7/8/10 virtual machine) where it still works, and access it from Windows 11.

If the application itself is no longer maintained and depends on APIs removed or changed by the recent update, there is no supported way in Windows 11 to “re‑enable” those removed entry points directly; the long‑term solution is either an updated version of the software or running it in an older, isolated Windows environment.
