MSIEXEC /f option can reboot machine

Citrix/Terminal Server rebooted after an MSI installed product was repaired using /f option, even though the property REBOOT=ReallySuppress was specified.

/f option ignores properties.

/norestart is not an option since it translates to the same property value, which is then dropped from the command line.

Use /i REINSTALLMODE=omus REBOOT=ReallySupress to repair a package without a reboot.

/i will achieve a similar function, and it will correctly use the passed in properties. A debug shows that /i with REINSTALLMODE=omus was identical to /fomus, if the package is specified via GUID.

 

Actually the two command lines do not both enter MsiReInstallProduct, however internally they both end up in ConfiureOrReinstallFeatureOrProduct and subsequently RunEngine, as you can see from the two stack traces:
