Something might be an issue in the install...
This is a procedure I wrote to get the most clean install possible:
Uninstall any version of ACT! from Windows Control Panel | Add/Remove Programs
Use the Uninstaller.exe from the ACT! KB 19338 (the exe, not the manual uninstall)
Uninstall .Net Framework (all versions) - this does NOT apply to Vista users as .Net 2.0 is part of the OS and can't be uninstalled
Uninstall any MS SQL items from the Control Panel if still there
Uninstall MSXML 6 Services from Control Panel if it's still there
Perform a Selective restart with MSCONFIG as per ACT! Knowledge Base AnswerID 14499
Install .Net 2.0 Framework (only 2.0 for ACT! 9/10) from MS web site (only XP, not Vista)-
Manually install MS SQL as per ACT! KB 19386
Install ACT! 10.0 full install
Install ACT! 10.03 patch if the previous install was the previous build
Restore from Selective Startup Mode with MSCONFIG
Reboot
