I am running Windows XP Professional 2002 SP3 on a desktop workstation connected to a corporate network. I downloaded the Office 2010 Professional Plus beta. I elected to do a custom installation and install only Publisher 2010. The installation completed successfully. I have been unable to activate the software. When I attempt to do so, I get the following message: "An unspecified error has occurred. Your request cannot be processed at this time. Please try again later. (0x8007001)." I have tried repeatedly. I have de-installed and re-installed. I was able to install and activate the product on my laptop.
1.) Start menu --> Run... --> regedit
2.) Search for this registry key (you might want to right click HKEY_LOCAL_MACHINE --> Find..., and type 4D36E967-E325-11CE-BFC1-08002BE10318 into the box):
3.) Look for UpperFilters, which is of type REG_MULTI_SZ
4.) Double-click on it, and under Value data, add "PartMgr" to the top of the list. Click OK.
5.) Restart your computer.
6.) Start Word (or any Office application), and follow the prompts to activate.
