I'm running Windows 10 on an 8th gen intel i7. I followed the instructions on the wiki for VS but after I ran

Code: Select all

CI/before_script.msvc.sh -k -p Win64 -v 2017

the .sln file was not created in openmw\MSVC2017_64. I checked openmw\MSVC2017_64\output.log.

Code: Select all

I just updated VS 2017 and made sure it had the C++ desktop module. Any suggestions?

Maybe try reinstalling CMake, too, and if that doesn't work, reinstall VS again. I used to have issues like this with lots of projects when VS 2017 was new, and after a zillion reinstalls, it eventually stopped happening.

Thanks! I just reinstalled CMake. The first time i used the zip and manually added it. This time i used the msi and it worked.
