I installed a full version of Crystal Reports 9 on Windows XP. When I click on the Open button on the toolbar or from the File menu nothing happens. Same thing with Save and Save As. If I open a report from Windows Explorer it opens and runs fine but I can't save it. The PC has had other applications installed that use redistributable versions of CR 8 and CR 12. I uninstalled all versions of CR and just re-installed CR 9 but get the same result.
Any ideas of how to fix this, other than rebuiliding from scratch?
