wyUpdate.exe error

I have copied the wyUpdate to 5 XP Embedded Computers, only 1 of the PC got error while running the wyUpdate.

Message "wyUpdate has encountered a problem and needs to close. We are sorry for the inconvinience"

Any ideas?

At what point did it happen (before any update started, or was it already far along in the process)? What version of wyUpdate are you using? Is the .NET Framework 2.0+ or 4.0+ installed (depending on the version of wyUpdate you're using)? Are you using the AutomaticUpdater, or wyUpdate as a standalone updater?

before any update started, error appear straight away. NET 2.0, 3.5 installed. Version 2.6.18.4wyUpdate as a standalone updater.

First make sure the machine has the latest service packs. Also make sure you're not overclocking the CPU or memory. Then you need to give us the full stack trace of the error.
