Anyone having issue with T-rex deleting the exe file?

I tried downloading and running T-rex a few days ago then decided to use NB miners. It works fine but have been hearing the T-Rex is better. So I tried again today and noticed once I edit the bat file and try to run it, it say "trex.exe is not recognized as an internal or external command, operable program or batch file".

I checked and the exe file was deleted from the folder. I extracted the file multiple times and it did this every time. I tried all the CUDA versions. Anyone else have this issue?
