Registry Hacks » How to kill pesky MSI roll-backs

(Note: before following this or any other tip on this site, please read the Disclaimer)

Ever encountered an MSI-based installer that, in spite of reporting some failure, actually does succeed in leaving you with something workable? Sadly any such stroke of seemingly good luck tends to be short-lived, as the next MSI you run – even if it’s entirely unrelated – compels you to roll-back that “failure” thus removing that workable something from your system. It lacks a way for the user to decide that marginal success is good enough, and the cycle of forced removal and near-successful re-installation becomes irritating in a heartbeat.

Using REGEDIT.EXE, browse to the following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\Rollback\Scripts

(Remove applicable string data items as desired.)
