Configuration Error

Hullo all, I’m a long time Scrivener user and I’m running into an issue I’ve never faced before.
I’m working off of a family computer while staying out of state, and since I cannot remember my purchase code for the life of me, I’m content to work with the 30 trial for the time being.
That is until I got a message saying
“The application has failed to start because it’s side by side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail.”

This happened the first time I tried to pull up the program after downloading and installing it. I’m totally clueless as to how to fix it, and I would be very appreciative for any and all help.
Many thanks,
