After searching for an MSI installer for this without success I was able to build this one which worked for me to enable non-admin users in a managed environment to run the SQL Server Reporting Services RSClientPrint controls in the browser.
My environment is SQL Server 2005 SP2 with Reporting Services.
Attached is a zipped copy of the RSClientPrint.msi file. (RSClientPrint.zip)
Hope it helps someone else. 🙂
