All of a sudden, all my t-rex folders on Windows are unreadable. I can't open to modify bat files. Is there a reason for this? Interestingly, right click and edit says corrupt file, however right click and notepad++ opens them. Seems like an issue local to my OS.
Ransomeware??
That's what I was afraid of. It was odd that it seemed localized to the t-rex install folders. I found no other indication of ransomware in the OS though. Following the "dism" cleanup/restorehealth steps from other people having run into the same issue fixed the problem.
I am glad you resolved the issue and that it was not ransomeware ot something like it.
