I'm using SB 7 and trying to run an MSI I've included as a support file using the following command:

Run Windows Installer %TMPDIR%\ASPAJAXExtSetup.msi /i

(/i is a Start Parameter)

_SB_ERRORCODE returns a -1. I can invoke this installer from a command prompt just fine with msiexec /i [file].

I'm including the MSI 3.1 redistributable (version 3.1.4000.2435) in my script.

I've verified that the msi file is getting put into TMPDIR.

To provide a little background info, we had an SB6 installation that worked fine. But our scripts somehow got deleted so we upgraded to SB7, redeveloped the scripts and are now having this issue.

Any idea what the problem might be?

Thanks!
