Avoid confirmation box in MsiExec uninstall

Question

I need to run the msiexec uninstall from my code:

MsiExec.exe /I{A52EEC0E-D0B7-4345-A0FF-574804C7B78A}

But this is asking for a confirmation (Yes/No). How can I avoid that?

Solution 1

msiexec /quiet will avoid the userinteraction

Solution 2

You can use the /passive switch to do this.

MsiExec.exe /I{A52EEC0E-D0B7-4345-A0FF-574804C7B78A} /passive

If you want to completely hide the UI, use the /quiet switch instead of /passive.

Solution 3

Try adding the /qn flags to your command line. /q is quiet mode and n is a flag for /q that suppresses all user interface.

With these flags added, the complete command would be:

MsiExec.exe /qn /I{A52EEC0E-D0B7-4345-A0FF-574804C7B78A}

Not fully correct. Yes, "/qn" is one of the possible parameters here. To give the full story here to all the answers: /qn and /q are equivalent- and /quiet is the same too. This is the silent variant. The second, unattended variant (with progress bar, but without asking or other modal boxes) is /qb or the equivalent /passive. All parameters solve the mentioned problem.

Of course there are more like /qb+ /qn+ or the variants with ("!") which is hiding the cancel button during progress (/qb+! /qb-!).
