I assume you logged MSI actions; what is the value of REQUIREDBINARIES property? Also, I'm note sure you correctly use the upgradecode (ID tag from the Upgrade element). That ID must be the UpgradeCode from the product you want to detect wheter installed or not; do you have that GUID?

This didn't work; the install always aborts, whether the required product and version are installed or not. I thought it might be a sequencing problem, so I got rid of the Condition and defined a CustomAction and sequenced it sequenced it so it should come some time after FindRelatedProducts, i.e., <CustomAction Id="CheckForReqdBins" Error="You must install ..." Return="check" /> . . <InstallExecuteSequence> . . <Custom Action="CheckForReqdBins" After="PreventDowngrading"> (NOT REQUIREDBINARIES) </Custom> . . Same result. I'm kind of fuzzy about the evaluation of strings as conditions, but something analagous has worked for me when the Upgrade is the product currently being installed. Assisistance appreciated.
