detect if current version was original or a patch?

I have 3 version of my product, v1/v2/v3.

v1 and v2 have been released. v2 included a v1->v2 patch.

After release we found a bug in the v2 patch that makes the system unstable
and would cause a v2->v3 patch to fail.

v1 original install is able to patch to v3, and a v2 original install can
patch to v3.

My question is, can a custom action in my v3 patch detect whether the v2
installation it is updating was an original installation or a result of the
buggy v2 patch?

If the bug is in the form of an incorrect file, maybe you could try
searching for that file using the AppSearch / Signature tables?

If not, maybe the ListOfPatchGUIDsToReplace property in the PCP file
would help you?

If you updated the ProductVersion each time, from something like 1.0.0.0 to
1.0.0.1, 1.0.0.2 etc, you could get the ProductVersion of the installed
product.
