Error - Microsoft Office 2010 does not support upgrading from a prerelease version of Microsoft Office 2010

Last week Microsoft released Office 2010. I have been using Beta and Release Candidate for quite some time and have been waiting for RTM version. So I downloaded installer from MSDN and launched it. Right off the bat, I get the following error dialog box.

---------------------------
Setup Errors
---------------------------
Setup is unable to proceed due to the following error(s):
Microsoft Office 2010 does not support upgrading from a prerelease 
version of Microsoft Office 2010. You must first uninstall any
prerelease versions of Microsoft Office 2010 products and associated 
technologies.
Correct the issue(s) listed above and re-run setup.

OK

I was hoping there will be straight forward migration from Beta to RTM. But fair enough that Microsoft wants machine clean of all Beta and Release Candidate installations. So I went to Control Panel and opened up dialog box to uninstall programs. Picked up the Beta installation of Office 2010 and uninstalled it.

I launched Office 2010 installer again, this time I got the same message again that I need to uninstall previous versions of Office 2010. After banging my head for some time, I decided to look at list of all installed programs and find anything that says beta. Bingo, there I found an installation of Outlook Hotmail Connector (Beta) as shown below in screen shot.

After uninstalling Outlook Hotmail Connector, my installation of Office 2010 went very smoothly. If you are running into same issue, make sure that any component related to Office 2010 that you installed during Beta or Release candidate, you uninstall all of those. Some of those components may not say Beta in their name. But if they are related to Office 2010, they need to be uninstalled.
