Hello and welcome to WeMod, first of are you using any AntiVirus(AV) program(s)? If so that is probobly blocking WeMod install and launching of the program. Some AV’s gives false positives on viruses with the WeMod app.
On a personal note, i myself use Bitefender as my AV and i gives me a few false warnings from WeMod when using it. The Staff have made a post on how to whitelist the WeMod for Bitdefender HERE.
I used WeMod today and it works fine for me.
