Hello,

I am writing a code which launches msiexec process.
I wonder what is the best way, using MsiInstallProduct or CreateProcess.
Does MsiInstallProduct call the same functions & actions order in the MSI as it is called using CreateProcess function? Are there any familiar restrictions?
Please advice,

Appreciate your help.
Thanks in advance,
Limor

I believe there's no significant difference between calling msiexec.exe and calling MsiInstallProduct, but the latter may be more suitable if you want to wait for the complettion of the instalaltion.

Logging is different. To get logging, you must call MsiEnableLog() in advance, but I never got the parameters right: when adding all documented flags, the log files were (almost) empty, and when adding 0x0ffffffff, I get even more log enties than Msiexecs' verbose logs. Further, the promised "flush after every 20 lines" didn't work - I have no idea how Msiexec manages to do so.
