This patch is no longer necessary with NSIS 2.45 and up
I have posted a patch for NSIS which fixes the issue in the upcoming Windows 7 Release Candidate (as well as build 7057 / 7068 / 7077 which were leaked early) where it would trigger a Program Compatibility Assistant warning. Only makensis.exe is altered... just replace it in the NSIS program directory. The updated manifest.cpp is included so you can build it yourself, too.

Thanks for this. Should we recompile the launchers for all of our apps as a more immediate solution than waiting for the new releases to include compatible launchers?

because there is still a lot that can change and then you'd have to do it all again. Windows 7 is early beta so it doesnt affect many people.

We're already using it for our official releases.

So, should this patch make it into the next official NSIS release or will you have to patch it too? I would guess something like this probably will go into the official release right, just waiting for a major release to put it in?

I don't think anything is going to change, since this affects the Release Candidate, something that isn't likely to change any under the hood before RTM. Also, it's not a bug, but a result of improved legacy installer detection in Win7. So again, not something that's going to change.
