After much testing, I've decided to upgrade our office (~100 users) to
Office 97 including Outlook.
Windows 95 machines have upgraded without problems. To upgrade NT
machine, I'm logging in as administrator to the domain from the users'
desktop PC. This is Windows NT 4.0 with SP 2 or 3.
I run setup from a remote CD mounted on the server. Installation goes
fine without a problem.
I reboot and have the user log in to configure his/her email. All
Office 97 programs work fine.
When I run Outlook, I get the message "The program is not registered
properly. Please run setup again. The file cannot be found."
If I run setup from the user's account, I get an error message during
setup about a problem with an Access .DLL file but Outlook will start
to work (Access still works as well). Unfortunately, if another user
logs in to that PC, Outlook won't work for them.
This doesn't happen on all NT machines. Just some of them.
