We use Tivoli to do remote pushing and installation of software to PCs, and the PCs are already loaded with WinXP SP3, DotNet Framework 1.0, DotNet Framework 2.0, and DotNet Framework 3.0. Tivoli will not perform an unattended install of DotNet Framework 3.5 SP1. It fails and the error logs
"DISSE0198I User program exit code: 1603
RGB9RAST -- Installation failed
RGB Rast:  Error: Installation failed for component RGB Rast. MSI
returned error code 1603"
I am using the parameters "/q /norestart". However if I log in to one of the PCs and manually run the Installation Files dumped there by Tivoli, after removing the "/q" , it starts off with this in the installation window--" "Download complete. You can now disconnect from the internet." and continues to successfully install. Can anyone suggest how to do an unattended remote install of DotNet Framework 3.5 SP1
Any help much appreciated.
