I have found that several patches I have applied to SQL lately (SP and Cum Upds) will update the RSClientPrint dll. This is unfortunate as it also appears to never be backward compatible so we have to push an MSI (that we must create ourselves) to all desktops at the same time we apply a SQL SP to the server. We can't push the MSI early to have the desktops prepared or they break in the currrent environment. This is combersome and I wish MS would correct. We set the package set to uninstall the old one and install the new one.
