After having some activation issues with draftsight 2017 yesterday, I tried uninstalling draftsight, which didn't work so I had to force uninstall it. Now I try to install 2018, but I get this error. This is the most recent error I get btw, I have gone through like 10 other ones, each time cleaning my registry and deleting every single file I can find coming with draftsight. Any ideas? I can't uninstall the program as it doesn't show up anywhere on my computer.
