Thanks for your help Quinn! And sorry for the slow response – I had to go to the hospital for the last 3 days. I’m fine! 😉
Frederik gave me this for you to try: https://animationpaper.com/files/AnimationPaper_x64.msi
He said, if AP won’t run after installation, please install this too: https://aka.ms/vs/16/release/vc_redist.x64.exe
We hope this will solve the problem. Please let me know if it worked or not?
