I need FM20.dll and FMENU.dll 32-bit versions to run an older app.

I need FM20.dll and FM20ENU.dll 32-bit versions to run an older app in Windows 11.

The app obviously requires 32-bit version of those files. I don't want to do uninstall / install different versions of original office just to be able to have the file, and restore everything back to Microsoft 365 64-bit.

I need FM20.dll and FM20ENU.dll 32-bit, only to be able to run an older app in Windows 11.

Hi @Hakan Yılmaz

FM20.dll and FM20ENU.dll are Microsoft Forms 2.0 components installed and serviced as part of a compatible 32-bit Office installation. Microsoft does not provide them as a supported standalone download.

Avoid downloading or copying these DLLs from third-party DLL sites. Besides the security risk, manually registering mismatched versions may not work because the application can depend on other Office components and registry entries.

Since 32-bit and 64-bit Office components cannot simply be mixed, the supported options are:

Ask the application developer for a Windows 11 and 64-bit Office-compatible update.
Run the application in a separate virtual machine or Windows Sandbox environment containing a properly licensed 32-bit Office installation.
If the application must run directly on this PC, replace 64-bit Microsoft 365 with the 32-bit edition. Microsoft documents that changing Office architecture removes the current architecture before installing the other one.

Simply obtaining those two DLL files is therefore unlikely to provide a reliable or supported solution.

Hope this helps, feel free to let me know if you need any further assistance

I have clearly told what I needed. You have provided every useless answer instead.

Meanwhile I have obtained the DLL files I needed, and the app is working as intended.

I understand, and I apologize that my response did not directly address what you were asking for. I’m glad you obtained the required files and that the application is now working as intended. Thank you for the update.
