I'm testing the Uninstall feature of our software (we use Helpware and
h2reg on installation). We use InstallShield for our
install/uninstall utility.

When I attempt to uninstall our software, I get the following error:
Internal Error 2753. h2reg.exe

I can run the h2reg -U command from the command prompt and it works
fine; however, when InstallShield runs it, it gives the internal error.

It may be relevant that we're registering (and unregistering) two
different collections (one for VS 2003, one for VS 2005).

Anyone seen this error before?
