How to get the needed registry values ?

a possible solution, maybe? Altiris makes a program called SVS, which creates portable registry "layers" during the installation of a program. I'm pretty sure that you can open up one of those layers in notepad, and see what registry entries were written there, rather than to you actual registry. Although this potentially makes any program portable, the software is only free for a trial version, but can be a useful tool for catching reg entries. Google for it, or search this forum, I'm sure there was already a discussion about this software.

You can also search this forum for registry tools, to see what others are already using.

Just take a snapshot of the registry before and after installing/running the app
and use regcompare to find the keys it creates .

There is also regmonitor, but that is from m$/sysinternals and it just shows you the keys that are in use ..

If you download sandboxie it writes all of a programs data in to a sandbox that doesn't affect your computer. It also writes a .reg store file at the root of the sandbox.
