Hi. I changed my anti-virus from McAfee to CA but afterwards Windows Installer would keep running. I tried unistalling CA but then found that Windows Installer would keep running trying to install in the last software that was installed. I contacted CA and followed their instructions to reinstall and now Windows installer keeps popping up trying to install the last component that was installed ('Please wait while Windows configures..). I tried using Windows Install Clean UP but this just moves the problem back one set of software (ie the most recently installed after whatever is removed by clean up).
Help would be valued.
