Ah thanks, think i got that confused yea.
So i downloaded MS .net4.5 fresh and installed it and Parsec still does not start. It opens a window checking for updates i presume, then just closes. No error, no nothing.
Are you sure the program is not open and stuck off screen? You can check the task manager and see if it running. Either way send me an email support @ parsecparser . Com and i can help you work through it.
