Click here to download the dialafix tool, once installed choose to Flush Software Distribution Folder. Then Click go to repair the windows update files, that will remove the update & let you install any other updates available. Which version on Powerpoint do you have Office XP, 2003 or 2007?

Unable to open live TV in HP PC Media Center

Look at the alerts in the security and firewall of Norton antivirus. It might be blocking it. also keep an eye on your bottom right corner when you attempt the live TV. Norton may be alerting you about the blocks in that area. Make sure you allow those connections. I would check Norton firewall and security before messing with the Windows firewall.

Bose lifestyle fault code 802

Here's what the Bose support website suggests.  Good Luck!
Messages displayed during a Music Information Update
Messages may appear on your media center display during a Music Information Update. If you see a message with instructions to call Bose, and a three-digit code such as "Error Code 802" or "Failed 172" while performing a Music Information Update, it does not necessarily mean there's something wrong with the system. Performing a media center reset and installing the update again may address the issue.

To reset your media center, follow these steps:
  1. Turn the media center off. Wait two minutes

  2. Unplug the power cord from the media center. Wait 30 seconds

  3. Reconnect the power cord

  4. Wait until "Bose Lifestyle" disappears from the screen

Note: After a reset, you will need to wait several minutes before playing stored music (3 to 20 minutes, depending on how many CDs have been stored). All other sources will be available immediately after the system powers up.

If you have any additional questions about these messages, please contactBose® Technical Support or call 1-800-278-1281.

Hpqthb08.exe and HPQDocViewer.exe error messages

****, since you have been having many issues, I guess that your windows is corrupted.

The best way to proced is to install a clean copy of Windows, install all of services packs and updates and then install the HP software and test the printer.

I know this is a lot of work, but it probably will solve this and many other problem that you are experiencing.

good luck!
