My DraftSight wasn't launching completely and would buffer indefinitely when I tried to open a file. I tried to fix this problem by restarting, shutting down, and even uninstalling/reinstalling the 2020 version of DraftSight. Only this did the same thing, so I uninstalled that version too. As I try to reinstall the 2020 version for the second time, this error opens up and cancels the install. How do I fix this? What is the cause?
