I was already following bellow articles.

I have tested by myself...

It is not working to export Excel and rtf format.

last thing, I did not include "Call DataReport"

It is working to export Excel and rtf format..

Why it is someting wrong?

I have installed sp0 and tested CRdesiner..

There are two things I want to confirm:

1) Confirm that adding "C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\win32_x86

" to the front of the path variable did not help

A : I already had that folder.

- I understand that folder exist, but is the path in the environment var? E.G; here are the steps I want you to try:

a) Go to the "system properties"

b) Click on the <Environment Variables> button

c) Edit the "Path" variable by putting the full path to the CR 2008 bin directory (...\win32_x86) at the front of the Path string

3) Can you export a "saved data" report to either xls or rtf in your app?

A : No, I can not export xls and rtf in my app.

- Understood. But, if you run the report in the CR designer, go to the File menu and select "Save Data with Report", then save the report. Now comment out any logon code in your app and try to run the saved data report. Does it run? Note: This is just a test to see how the behavior on your computer compares to others.

I need to be clear about all of the above as this is a new issue that we can not reproduce in house. Thus I need as much info as possible so I can compare your issue to those reported by others on this forum.

One other test. Let me know if you can export to .DOC file format...
