Re: msi in a Windows Service

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

My guess would be a security issue, your service is running in a completely
different security context.

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.
