I am attempting to determine if a specific version of a product is already installed on the system. I basically want to do this to disallow/bail out of an install if the MSI that is being executed is already installed on the system.
Here is my authoring using 3.0 RTM. I must be missing something simple: Upgrade table. FWIW, Product and Upgrade GUID is not changing for each build; only GUID that is changing is the Package GUID. Language attribute matches as well. <Upgrade Id='$(var.UpgradeCode)'> <UpgradeVersion Minimum='$(var.ProdVer)' IncludeMinimum='yes' Maximum='$(var.ProdVer)' IncludeMaximum='yes' OnlyDetect='yes' Language='1033' Property='SELFFOUND'/> </Upgrade> Check to see if product previously installed *and* is this specific version. <Condition Message="We be here!">Installed AND SELFFOUND</Condition> Thanks. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
