Software Deployment

Im using this : PSEXEC \\x.x.x.x msiexec /q /i c:\some_app.msi

Just thinking out loud...
Hmmm, not sure about using an IP address... ;) You might have a syntax error. I use this in a batch file (as an example for you):
psexec \\machinename c:\windows\system32\msiexec.exe /unregister

This will use PSExec on the LOCAL machine to run the msiexec on the REMOTE machine (\\machinename) to unregister the WI Service. I also use the full path to the msiexec.

If your path has any white spaces in it you should put it in double quotes.

You could also add an MSI log file (/l*v c:\temp\some_app.msi) then look at the full paths to see what is causing the 1603.

You might have a permissions problem too.

Well, I alway use IP Addresses and not hostnames due the the fact that sometimes i can not access the system via dns. So i have done this before via IP Address and it has worked.

Any other Ideas?
