I've been running Designer for years with much satisfaction. About 9 months ago I upgraded to Windows 7 and can no longer run any Repository Reports. I am running Designer Version 10.1.2.5 with Configuration 126.96.36.199.0 running on Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64bit Production.
When I run any Repository Reports, they fail with a Windows 7 pop-up message saying "Reports Runtime has stopped working. A problem caused the program to stop working correctly. Please close the program." followed by another pop-up that "CDI-21338: No results to preview".
I went through the process of re-installing Designer but no improvement. Do I need a new version of Reports Runtime? Where should I get it from?
Do you have Windows 7 32bit or 64bit? Oracle Designer is only supported on 32bit Windows (supported does not mean it will not work on 64bit windows)
Have a look at metalink/My Oracle Support note: "Error CDI-21338 When Running Repository Reports [ID 295618.1]" since the error can have several causes.
