MSI (s) (7C:84) [11:56:05:794]: Machine policy value 'DisableRollback' is 0
Action ended 11:56:05: InstallFinalize. Return value 3.

4. Process monitor log shows: ACCESS DENIED to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

5. Checking permissions of HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run shows that none has Full Control permissions.

Cause

Antimalware software is blocking all users from writing to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Solution

1. Disable any antimalware software installed on the machine.

2. Grant Full Control permissions on HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run to the current user and SYSTEM group.

3. Reattempt installation. It should finish correctly.
