I've recently reinstalled Win7 on my HP Pavillion dv6 laptop and I keep getting this cryptic message from HP support assistant shortly after startup. The computer seems to be working fine otherwise (if a bit slow).

error window

Detailed message with Event Viewer:

  • Look if you can find a better message in the Event Viewer.

  • Why? It’s a .NET unhandled exception. The details are not helpful. What is clear is that the exception is due to an XML file. The HP assistant should be uninstalled and the current version installed.

  • More than likely you have an outdated version of HPSA, download and install the latest version....www8.hp.com/us/en/campaigns/hpsupportassistant/hpsupport.html

The "cryptic" message is due to a problem with an XML file. Reinstall the HP software. If the error persists, contact HP support.
