I am trying to install Revit 2015 on a Windows 8.1 x64 computer. After MANY hours of troubleshoting I decided to simply format the computer and start with a fresh version of Windows 8 (upgraded now to 8.1) and I'm still having the attached problem.
I have tried the following things:
1. Instead of "install now" I tried "download now". No difference.
2. I tried moving LiteHtml.dll to c:\windows\syswow64 and c:\windows\system32 (one at a time, then both, neither helped).
3. I tried running setup.exe as an administrator.
4. I tried running setup.exe as an administrator in compatbility mode for Windows 7. No difference.
5. I tried running setup.exe as an administrator in compatiblity mode for Windows XP (SP3). I no longer get the attached error message and the setup starts to load, but then I get a message saying that this product is not designed for my operating system.
6. I installed all visual c++ runtimes from the 3rd party installs folder. No difference.
I'm about to go crazy here. What am I missing?
