Hi Souvik,
This appears to be a Windows issue, where something in the registry is invalid. I googled the phrase, and found a few similar issues for other software, but they all followed the same general path to resolution:
try browsing the registry (Start > Run > regedit > OK) to the following value:
Code:
HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products\<ProductSQUID>\
Where 'ProductSQUID' is the ID of the game (you'll have to go through the whole list of values, a daunting task) and check if there's a 'transform' entry on the registry key you believe to be created by the installer. Check if this entry is pointing to a valid Windows installation drive (where Windows is installed, most often the C: drive), and if not, change it.
As always, please be careful when making changes in the registry, make a backup, and contact your IT group if you do not feel comfortable doing it yourself.
