I have a client that is using ACT! 9 and Outlook 2003. Up until today everything had been rather peaceful on his machine. Every morning he boots his computer and is greeted by a fully functional and error free launching of ACT! and Outlook. Every evening he gently shuts the computer down and all is well. Today he boots up his computer and ACT! comes up as normal, however Outlook is now reporting The add-in "C:\WINDOWS\system32\Act9Ext.dll" could not be installed or laoded. This problem may be resolved by using Detect and Repair on the Help menu. And Outlook is now taking up 100% of the CPU time, is unresponsive and takes up all available memory. The client calls me for help and I remote control his machine to verify all he says is true. I then log him off and log in using a domain administrator account and launch Outlook. Lo and behold! The issue finds me too, the only difference is that I'm able to navigate around in Outlook and it does give up using 100% of the CPU time after it fully launches. I go to Help -> Detect and Repair and run using the default settings, no fix. I verify that the file it's looking for in fact exists, and it does. I try to install the add-in again, but there doesn't seem to be an Extension Configuration File for the Act9Ext.dll file. Any suggestions?
