I reinstalled Act 2007 several times and did not solve the problem. I use Act 2007 with Outlook 2000. Everytime I close the email it gives me a actemail.exe error. I have the option to debug or send error report to Microsoft and I have done both. When I try to reopen the email without closing Act I get a message cannot find installed email carrier on this computer - you have not setup any email system - you will need to install email before you can send or receive Act email. Any ideas to solve?
