My experience with it comes mostly from repackaging applications for automated deployment, but I can tell you that this could potentially be very difficult.  I don't expect anyone will be able to give you simple instructions, at least not without examining the software package first.  I will take a look at it, but no promises.

Checks of this type are usually a "custom action" -- a script or small executable is extracted and run by the installer. Depending on its exit code, the check is considered passed or not.

I should also note that the install time check may be just the first check and a courtesy measure to keep you from installing something that won't work.  It is quite likely that there also is a run time check.  Even if you get around the install check and install it, it may refuse to run.  Software vendors whose primary business model is bundling their product with hardware tend to be diligent making sure it can't be used without the right stuff.
