There are some tools that can detect reg when installing a application or games.. You can use that tool to get the reg and then you can covert that reg entry to inno setup format... This way you can add reg entries to inno setup easly.
I use Regshot tool to detect the reg entry
http://sourceforge.net/projects/regs...regshot/1.9.0/
And reg to inno convertor to conver reg files
