Hello,

last night my windows self updated. Since then i am unable to open any of my projects. I have tried to reinstall Archicad a few times but the same error message pops up at the end of installation. It says a "archicadSupport.dll" file is not found, even tho it is located in the archicad folder.

I am uneable to figure it out and need help as I have a project due in a few days a really need to work on. Thanks

Operating system used: Windows

Hello try to install additional third-party files, specifically Microsoft Visual C++. I don't see my answer in the thread (my post about same problem) you replied to. But here is what helped me:

go to the microsoft website: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170
Download the x64 and x86 Microsoft visual C++ 2019 Redistrubutable files
Install both files
Then restart the computer and Archicad should start

I hope it this helps
