Sounds like some annyoing antivirus program issue.
Try to exclude the vorpX program folder from your AV program, typically that’s C:\Program Files (x86)\Animation Labs\vorpX
BTW: If you happen to use any other AV program than Windows Defender, the best you can do is getting rid of it as fast you can. There is no need for (usually more invasive) third party AV on Windows 10. Windows Defender is more than good enough since several years now. It kicks in automatically when you remove redundant third party AV.
That’s not the problem, I’ve already uninstalled my antivirus and it’s still not working. Is the setup program broken? Can I get a link to a new one? I literally can’t even launch the program I paid £35 for, I’m going to have to request a refund if there isn’t a solution.
