It seems Paint Tool SAI does not like Windows 10 at all, because when I tested it on the beta version of Win10, it wouldn’t run at all. If you use SAI as your main drawing program and wish to continue using it, then I strongly suggest you avoid upgrading to Windows 10 until somebody finds a way to get it to work on there. It’ll be a real bummer to see anybody having to struggle with the loss of SAI because of a Windows upgrade that it’ll refuse to work on.
Same with windows 8.1. this trick might work:
find the .Sai exe, right click, and select troubleshoot compatibility .
It’ll take you through a few steps after that. It should be able to open the program. But the problem I had after was loosing Pen sensitivity.
I’m not sure if that’s due to upgrading to a newer intuos , or if its part of the compatibility issue, however if its not i hope that might work
I’ll throw this out there too. I had upgraded to Windows 10 last night and heavily lamented the fact that I couldn’t open SAI. I saw this post and lo and behold, troubleshooting it worked!
However, I’m not sure if this will happen to everyone, but I was using Windows 7 with SAI and the Windows 7 compatibility mode didn’t work. I tried inputting Windows Vista compatibility mode and SAI works fine now.
Just a little thing I figured I’d throw out there in case anyone has any difficulty!
