REINSTALLMODE=vomus


What is the importance of ‘v’ in REINTALLMODE?

msiexec /i test.msi REINSTALLMODE=vomus REINSTALL=ALL

The important part is the "v" in the reinstall mode settings. It forces the use of the new msi
file instead of the cached copy.

If you are upgrading a package with same product code and different package code(ofcurse) use ‘v’ inorder to recache the new msi.

    Hi Sir,

    Just to add on when we have transforms with MSI, the REINSTALLMODE=’v’ does not apply to transforms getting recached.

    I had this issue once where the production machines were affected due to earlier packages and the only way to uninstall it was manually change the transforms on the machine using scripts.

    Seasons greetings and a Happy Newy Year Sir!
