Sony Vegas Pro 12.0 Installer not opening

I went to Sony's website to download the trial version of Sony Vegas pro 12.0, and it downloaded me the installer. So i double clicked the installer and a small screen popped up asking do i want to let this program make changes to my computer. After clicking yes, nothing happened. No error sign, no nothing. So i went to my Task Manager to check and there it was. On the process section was a thing called vegaspro12.0. but i couldn't do anything else with it than close it. Also if i open the installer, lets say three times, there's three vegaspro12.0 in the task manager.

Any help is needed.

Just a guess - check to see if you have the latest version of QuickTime installed. There is some sort of weird dependency between Vegas and QuickTime - check the Vegas System Requirements list to see it.

Downloaded the newest update of QuickTime, still the same. Thanks for trying though, i really appreciate it.

Then try doing a full un-install and re-install. You'll have to do some registry tweaks to accomplish this, but they are simple and safe since they only affect Sony software.

Deleted all the files i could find but still the same. Thanks for trying though.

I got frustrated and asked the files from my friend and now it works. Except when i try to actually open vegas the normal loading screen comes up but it just stops to ''Initializing UI...'' and nothing happens. But if i wait for like about 10 seconds, in to the top right corner of my screen pops up an empty window called ''SfVstServer''. Any Idea why?

Well i searched my computer for viruses and nothing was found. Then i restarted my computer and it still froze to ''Initializing UI'' but the ''SfVstServer'' window never came up. Any idea why?
