Epic games is not a valid short file name

This all started when I was purchasing Borderlands 3 Ultimate Deluxe edition. Before I’ve never downloaded the Epic games Launcher so when I started to download it, the launcher trying going straight into a D: drive and not my C: drive which is the ONLY drive I had. I wasn’t sure what do to because attempting to change the location wasn’t effecting it. It would just keep attempting to go into my D: drive. I then decided to delete all the epic games installers that tried to run, not however I can’t even download the launcher from my windows because it’s now saying “epicgames is not a valid short file name”
I’m torn on what I should be doing. I don’t know enough about computers to really stove this issue. If someone has anything close to a remote answer please let me know, I REALLY don’t want to refund.
