Hi,

I got a strange problem. I use Macrovision installshield x express
edition to build a simple MSI file. I can install this mis silently, i.e
using /qn. It has no problem to run either in the command prompt or in a
windows application. However when I put the same code to run this msi in a
small windows service, it does NOTHING !!! It only starts the thread, but it
does not do installation.Why?

Here are codes:

Dim psi As New ProcessStartInfo
psi.WorkingDirectory = MY_WORKING_FOLDER
psi.FileName = MY_FILE_NAME
psi.Arguments = "/qn"
Dim p As New Process
p.StartInfo = psi
p.Start()

Thanks in advance.

Click to expand...

what's in the installer log?

to add logging - add following command-line parameter:

psi.Arguments = "/qn /l*v logFile.txt"

logFile.txt - will contain verbose log of the msiexec, where you can see
what is happening
 
I turn on the logging of Installer in OS. It doesn't generate any log files.
So my guess is that somehow install is never started although the process is
started.
 
This is my guess too. But I have no documents/links for this help. Please
let me know if you have any clues/documents/links about this security issue.

Thanks!
