|BUG: MSIEXEC.EXE - Setting Property Values to NULL|
Be careful when setting public properties to NULL (empty strings), if you try the following (tested WIN2000 and WINXP):
msiexec.exe /i somemsi.msi SOME_PROPERTY=
Then "msiexec.exe" will stuff up and assign some garbage to the property, a work around (as documented in Windows Installer doco) is to do the following instead:
msiexec.exe /i somemsi.msi SOME_PROPERTY=""
