Read through the solutions, nothing seems to be what i'm getting. I'm on Windows 7 Ultimate x64, and Ive got the latest version of windows live, other msgplus versions install fine but with this new one as soon as it's downloaded and I want to open it a instilation sized box pops up but is just white. no icons nothing just a white box, ive left it for like 15 minutes and it does nothing. Only way you can close it is through task manager. Just a quick heads up, ive ran malware spyware checks etc, redownloaded it 8 million times, run it as administrator, run in compatability of about..every option on there, nothing .. just a white box.

Any help would be great! cause i'm rarther stick : D
