I hope it's okay to post about (yet another) compatibility issue with Vista! Some of you may know already, but the latest version of Adobe Reader (Acrobat DC) only supports Windows 7 and later. However, I extracted the installer and got an MSI out of it. I edited the MSI with Orca and removed the NT 6.1 restriction, and it installed without errors. However, getting it to run is a different story. Judging by the error message attached, it appears that there's a missing call in USER32.dll called GetTouchInputInfo. I don't know if it can be stubbed or not, and I lack the necessary skills to do it myself. Would anyone here be interested in stubbing this call (or even finding out if it can be done)? Any help is greatly appreciated.
