Sony Vegas Pro 9 Trial Won't Install

I've seen several other threads on this around here, but none of them seem to have any definitive answers. Anyways, I downloaded a Vegas Pro 9 Trial directly from the vendor's website (Sony obviously) and started the install. I ran as administrator, and got to a point where it asked me to install several "Required Components". I clicked OK to install, and quickly got this error message. I have Windows 7 Professional, which I bought legitimately.
Please Help!

I'm not using any cracks on Vegas, it's clean downloaded straight from Sony and I'm just trying to use the free trial. However, Vegas Pro 8 was installed and cracked on the same computer. It has since been removed, and to my knowledge there aren't any traces of the install or the crack on my computer. I believe that Vegas says it wants Visual C++ 2005, Visual C++ 2005 Redistributable, and Visual C++ 2008. I'll check those in a little bit, I'm away from the computer that has the problem right now but I'm 99% sure that's what it's asking for.

This thread shouldn't be under the Gaming forum SF moderators, Sony Vegas is a 'Pro Video' editing app. :)

Sony Creative Software - Vegas Pro 9 - Introduction

Make sure you are running an un-cracked/patched version of Windows 7. If you are this will never install. (For reasons that are obvious), I will not discuss on how to get around this problem, because it would be contributing to piracy. If you are running a "TRUE" windows 7, just update or install Dot.Net 3.0.

Ok, this worked for me, but it may not work for you. You downloaded the 64-bit version, correct? Well, download the 32-bit version. Once you have installed that, then you should follow this video: YouTube - How To Get Sony Vegas Pro 9 For Free ( HD Voice Tutorial ) - Full Version With Effects Hope this helped!!

try this
right at the moment when the C++ 2005 thingie says it failed (don't close it) you can find the Temp folder where the installer put all the files (it'll all disappear if your Vegas installer quits)
- find 'vcredist_x86.exe' online (or for 64bit if that matches your setup) & install it
- open any windows explorer, type in %TEMP% in the address bar (this will be your Temp folder for installs)
- open folder 'SonyInstall_1' and right click on 'vegas90.msi' (RUN as Admin)
- worked for me (using setup.exe didn't work this way)
