I was having an issue with all languages where VCS would say “fatal error: ‘chrono’ file not found” (along with some other more detailed output) any time I’d try to compile. Uninstalling did not fix the problem. I couldn’t find any other threads about this problem so hopefully this will show up in search engines and help other people.
C:\Users\%USERPROFILE%\AppData\Local\VEX Coding Studio
and delete the folder “VEX Coding Studio”. So, specifically, you want to delete
C:\Users\%USERPROFILE%\AppData\Local\VEX Coding Studio\VEX Coding Studio
. Not sure if there are unintended consequences if you mistakenly delete the parent folder.
This fixed the problem for me. Credit to jpearman for posting this process in another thread.
