.dxf not opening/converting in Acrobat Pro on Win11

[A-nun-ymous]

My company recieves pattern files as .dxf from our factory across seas, our patternmakers used to be able to open these and convert to .pdf by right clicking them. Since upgrading a few users to Win11 they are no longer able to do so. Acrobat gives an error "Conversion of this file format to PDF is not supported on 64-bit version of Acrobat."

Other posts have suggested downloading the latest VC++ files from Microsoft, but even after completing the installation on two users computers and restarting the device, this functionality is still missing. I've verified the same packages are installed as our Win10 machines that still open and convert these files to PDF's as they have for years. I have also tried Creating a new PDF > Importing .dxf files as suggested in some other posts but it results in the same error message in my intro. 

The obvious solution would be to ask the factory to just export as .pdf but apparently they charge per thing they do and that's way above me. Our test-users also have access to Illustrator which supports .dxf files but they don't typically use that product in their workflow.  Please help me find a solution!

Hey folks, to anyone also struggling with this very very niche situation.. I have found a solution!!!

Please note this only seems to work with 32bit Acrobat.
Install all Visual C++ installers, I found it easiest to get them here: https://www.techpowerup.com/download/visual-c-redistributable-runtime-package-all-in-one/
Then all the X86 .net 6 installers: https://dotnet.microsoft.com/en-us/download/dotnet/6.0
restart computer

Last step is Registry entry
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\FeatureState

note: don't go to the top level Adobe in Registry, go down to WOW NODE, and within that folder select Adobe > Adobe Acrobat > DC
Add a new key to DC

Update with d word 32bit

- bEnableODAWorkflow, change value to 1 (true)

Restart. 
Now when right clicking .dxf files you'll have the option to open them as PDF's in Acrobat!

I'm having the same issue. Let us know if anyone knows how to fix a 64-bit install. I could open it in Illustrator and save it as a PDF, but not all Acrobat users have the Suite.

Looks like it broke again, none of our users can convert now... SIGH
Not sure if 64 bit supports this type of conversion. 
I'm looking into using Zamzar, very quick conversion and no fuss.

same problem, Acrobat will say it's not working with 64bit version..
