Using group policy to do software installations, there is an option to select that will install an app over the top of an existing app eliminating the time needed for the old one to be uninstalled before the new one is installed.
Group Policy software installations for us are a 50/50 chance that it will work or will not. We are trying to use a third party script editor to run our update using MsiExe.exe, but the only success we have had is with it uninstalling the old and then installing the new. The command we have is msiexe.exe /i appname.msi /passive /norestart TRANSFORMS=transmform.mst
Does anyone here know how to use this command so that the installation will install the new version over the top of the old one with out uninstalling first?
Thanks,
Steven
