I've been using ScreenToGif for a while across all my machines.
Today I tried to replace my existing ScreenToGif.exe (which I located at C:\Program Files (x86)\ScreenToGif) with 2.5 (which I renamed to ScreenToGif.exe, as I always do...I have a short cut on the taskbar for it).
My machine is Win10 14393.693 x64 (latest released). Has all updates, etc.
When I try to open this, it fails immediately with the same issue as this:
On a hunch, I tried to start the executable as admin, and it appears to be a different app...some kind of translator that is downloading language packs?
See attached screenshot.
