Hi Phil,
Thanks, the permissions were all good so I tried deleting (renamed the old file in case I need it for anything) and restarting and its generated a new one and the message is gone Thanks for that.
Hi Jo,
Thanks for the reply, I can't find Report.tmp but ReportViewer.exe is present and runs but gives the message Report.tmp was not found when I run it. I've asked the Network Admin about AV Software but believe it is just Windows Defender.
