They may have a fix or patch. But there are things I try which you can google about.
1. Run the app as Administrator.
2. Try the App Compatibility settings. https://www.google.com/search?q=Change+app+compatibility+in+Windows+10
I have a very old VB6 app I had to run in the XP SP3 compatibility settings. No one told me or documented it so I tried Windows versions until I found one that worked.
Hello, I've been using a program on my computer called DesignDoll for my art. http://terawell.net/terawell/
The program has worked perfectly fine for years until recenty the program turned into a little white box in my task bar and it refused to startup again. Every time I would attempt to start it this popup would appear
I completely uninstalled and attempted to reinstall it but the same popup shows up so I can't even reinstall it anymore. I've pretty much completely erased the program and anything to do with it from my computer and yet I still cannot reinstall it. I don't really know what to do anymore, this program is extremely important to me and to have it just stop working entirely really sucks.
