Launcher Won't Load without Admin Privileges

[WubMeister]

I just bought the Initiate Pack and installed the launcher, but it says there's something wrong and that I have to reinstall the launcher. The trouble is that it actually works on the administrator account. Since it's my parents' computer and I am (for some reason) not trusted to have an administrator account, is there any way I can play this game on my own, normal account?
