That Enterprise version comes with stellar support, a personal contact at Microsoft and fast replies. Call them so you can get it fixed now.
I use Windows XP Professional and had Office 2007 Enterprise installed and working perfectly. This was not a trial version. I started having a problem with MS Word. I tried repairing and it did not help. I tried uninstalling and reinstalling Office 2007 Enterprise and now it will start installing but will not finish. I get message "error 2350. An internal error has occurred." I googled this error number and it had to do with windows installer. I installed latest version of windows installer and still have the same problem. I try canceling the installation and it will not roll back. I have to shut down and restart computer. I can install the old Office XP Pro version but would prefer to use the Office 2007. I also tried installing Office 2003 but it does the same thing as 2007. CAN SOMEONE HELP ME PLEASE?
