Sony Vegas Pro Installation Idle Problem

Yesterday I tried to install a video editing software, Sony Vegas Pro 11 on my Windows 7 32-bit SP1 computer. After trying hours, it won't install. The problem is the installation always got stuck on "Please wait for initial configuration of Vegas Pro 11.0. This might take a few moments". I looked at task manager, the process was completely idle. I even downloaded Sony Vegas Pro 10 and it's the same.

At the time when I almost reach the top desperate point, I decided to do system file checker with "sfc /scannow" command through command prompt. Guess what, it returned error too! The error message is "Windows Resource Protection could not start the repair service". So I dug the internet, again, trying to resolve the issue with solution from here and here, they don't fix it. The next problem came up is "Windows Modules Installer" which is needed by System File Checker can't start. So here is the actual solution for the issue:

1. Open Registry Editor aka Regedit
2. Go to "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control"
3. Find a key named "RegistrySizeLimit" Type: REG_DWORD
4. Change value to 0xffffff (4294967295)
5. Reboot

After reboot, the Sony Vegas Pro installation ran smoothly.
