My wife's computer is a DELL Insperon 530s with a Pentium Dual Core 1.6 GHz E2140 Processor, 250 GB SATA II Hard Drive and 2GB DDR2 SDRAM. It came with XP Home installed.

The software is up to date, and has all published updates installed. It is used in our home, and she is the Computer Administrator. She is listed as the administrator on the User ACCOUNTS screen. I have also verified that she is the administrator by following Microsoft's instructions and running "timedate.cpl". Microsoft says that if the clock opens, which it did, you are the administrator.

Among the installed updates is Media PLAYER 11, with several updates to the player.

But, Media Player 11 cannot be opened. No matter what method I use to try to open it, I always get the same warning screen that tells me "to FINISH installing Windows Media Player, restart your computer and then log on as an administrator".

I am at a loss as to what to do. My wife is the administrator, and I don't know how to log on again as the administrator to complete the player installation.

Or is there something that I am missing.

Thanks.

0708Try downloading Media Player 10 at http://www.microsoft.com/windows/windowsmedia/player/10/default.aspx. Then, you should be able to use the program or reinstall Media Player 11 if you so desire through Windows updates. If that doesn't work, you may need to restore you machine to original factory defaults since there could be some operating system corruption.Go to Add/Remove Programs and uninstall it, then download and install a fresh copy.Download the fresh copy of windows media player 11 (genuine) and install it. If it asks you to restart and logon as administrator, here is some trick.

Restart your computer and whenever the logon screen appears press CTRL+ALT+Delete
then a logon window appears. In the USERNAME type "administrator" (without quotes) and press enter (If you don't has administrator password set at the time of installing os it will work). Now you are the administrator and you can install the software. Be sure that no administrator password is set.
Thanks to all of you for your advise. After more time than I can imagine, and running more Microsoft programs proving that my wife was the Administrator, I still could not resolve this issue.

So I took the easy way out and following Microsoft's instructions, I rolled back to Media Player 10, and blocked further updates to MP 11. MP 10 works.
