Repository reports cannot generate HTML report

Question

Hello
In our Computing Labs, we have Oracle9i Designer installed on Windows XP Professional.
Our students are having a problem when they try to Run Report in Repository Reports.
The student first sees an error message for Internet Explorer that says "Cannot find "file:///c:/docume~1/%username%/LOACLS~1/Temp/ck*.tmp.html". Make sure...". %username% of course being the current user and ck* being the filename of the report.
If the user examines the contents of ~/Local settings/Temp, they will see that when this error message comes up, there is a file ck*.tmp (no HTML extension). The HTML file is never generated though.
When the user click on the OK button for the error message, Internet Explorer open to a blank page. When IE is closed, Repository Reports posts a message that says "CDI-21309: Unable to delete file c:\docume~1\%username%\locals~1\Temp\ck*.tmp.html". When the OK button from this message is clicked the user is returned to Repository Reports, but the report is never generated.
Our users are set up as Dynamic Local Users, and are members of the Power Users group. We do have some pretty tight restrictions on Group Policy.
When a user who is a member of Administrators (also dynamic local user) logs in and attempts to create a report, (s)he has no problem. Repository Reports functions exactly as it should.
I have already given Power Users complete access to all files on the hard drive, so I don't think it could be an NTFS file permission issue.
If anyone has any advice, it is certainly welcome. Our students need to be able to print off these reports for classes, and I am not familiar at all with Designer.
Thank you very much

Answer 1

Here is how I resolved my problem with non admin users not being able to run reports.
Designer 9i ver 9.0.2.80.6
Repository Reports ver 9.0.2.80.4
Problem - When non Administrator users try to generate a report in Repository Reports, they either get a file not found error for the HTML report (and IE will not show the report) or Repository Reports stops responding (and rwrun.exe has to be manually killed).
Fixes
-%TMP% and %TEMP% environment variables must resolve to paths that are fewer than 30 characters. In our environment (WindowsXP with Novell Dynamic Local Users), %TMP% and %TEMP% were the temp folders in the user's profile, which is a long path. Changing the environment variables to point to c:\temp was one step in resolving the issue. Although there is a patch released related to this, my installed version is post-patch and I still had to change the temp environment variables.
-HKLM\SOFTWARE\ORACLE\HOME0\REPORTS_TMP must be set to a writable area for the user group using Designer and Reports. In our environment it was set (during install) to the local administrators temp space (in administrators local profile) - I'd guess it gets set to whatever %TMP% or %TEMP% is for whichever user installs the application. Our users cannot write to this folder, so setting this registry value to c:\temp was another step in resolving the issue.
-c:\OraHome1\reports\logs must be writable for whichever user group is running Reports. Before making this change but after making the previous two changes, reports would simply freeze for Power Users. When trying to log off, rwrun.exe had to be manually killed - and sometimes a Dr Watson report would come up and ask to be sent in. By granting the user group that uses Reports write permissions to this folder (or the equivalent in your environment), Repositry Reports no longer freezes and successfully generates the HTML report.
