Adobe CS5: Installer failed to initialize

When you try to install Adobe CS5 products, you might get an error like: "Installer failed to initialize. Please download adobe support advisor to detect the problem". Downloading the support advisor didn't help me because it showed me what OS version I'm running, and a link to adobe support. Hmm.
Here is what you need to do.
1. Goto to your temp directory. (Press Windows+R key and type %temp% and press enter).
2. Open the file PDApp.log.
3. Look for any [Fatal] entries.
4. What I have got is that the installer wasn't able to create C:\DOCUME~1\username\LOCALS~1\Adobe\OOBE\PDApp\PDApp.exe.
5. Now create those folders for the installer, and run the installer once again.
