New version of crystal report clashing with old one

Hi,

I have the old 64-bit version on my pc but when I try to upgrade to the newer version, the old version gets uninstalled. but the new will not run reporting for applications that ran perfectly well on the old version.

i did uninstall the new version and installed the old version and my reports ran perfectly.

is there a way around this? as I need to upgrade to the newer version for an application that also only runs on the new version.

can anyne advice pls.
