Oracle Error REP-00118: Unable to create a temporary file.

I received REP-00118 error when using Reports builder in remote desktop. ( Limited user access)
Following steps helped in resolving the error..

1.Create one temp folder in C drive.
2.Go to RUN, type the regedit and press enter  ( Windows XP)
3.It displays a Registry Editor and press CTRL+F
4.Search for the REPORTS_TMP and right click to modify
5.Give the path of you created temp folder.  e.g. c:\ytemp

Hope this helps!
