[wix-users] Patch installation behavior

[Fyodor Koryazhkin]

Hi,
I want to share what I have discovered recently: During installation of
patch through command line (msiexec /p <path_to_msp_file>) if  INSTALLDIR
parameter is added to command line then installation runs in maintenance
mode and patch is not being installed.
Of cause there is no need to pass this parameter during patch installation
but nevertheless I did not expect such a behavior.

Has anybody else familiar with this behavior?
