Visual Studio Installation Error - Check that you have permissions & enough space in Visual Studio directory.

I was installing Visual Studio 2005 on a Windows 7 Enterprise machine and I got the following error during the installation process -

Reason -

Visual Studio 2005 setup was run from a ISO image mounted to a virtual drive on Windows 7. Apparently, Visual Studio installation has some permission issues when started from a virtual drive.


Resolution -

Easiest option is to burn the ISO image to a DVD & install from a DVD disc.
