Error 1731 During Office 2010 Installation

When you upgrade Office 2010 from BETA to RTM, you might get Error 1731 the source installation package for the product Microsoft Office Office 64-bit Components 2010 is out of sync with the client package as shown in this screenshot.


This is because there are still pre-release Office 2010 products installed in system. It could be BETA or RC version of Office 2010 products.

To get rid of this error, simply go to your Control Panel/Programs list and remove all Office 2010 products (including Visio, SharePoint Designer) listed with version lower than 14.0.4763.1000. Once all pre-release Office 2010 products are completely removed from your machine, you will be able to install Office 2010 successfully.
