We use Crystal 8.5 in the same environment. The control file is the .crf file I believe. I've run across situations like yours. After making sure the problem users have run the setup.exe file I have often solved the problem by copying: Working user \ home drive \ windows \ crystal And copying the crystal folder to the same location for the problem user. _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Kevin Droz Sent: Wednesday, June 08, 2005 11:43 AM To: Thin@freelists. org Subject: [THIN] Crystal Reports Were running Crystal Reports 8.5. I'm using the complied reports module to make the reports .exe's. I'm trying to run these reports as shared application in Citrix XPa/Win 2K SP4. For some reason, I'm getting a random error sometimes when executing the report. It states "no control file could be found". The report will work for one user and not the other. Any ideas? Thanks, Kevin.
