I"m trying to install the updates for windows vista ultimate, and a msg box pops up saying "wusa.exe - unable to locate componet... this app failed to start because dpx.dll was not found. Re-installing the application may fix this problem" right when it gets to 98% or so... if i press ok, another msg box pops up and says "windows update standalone installer has stopped working...... a probelm caused the program to stop working correctly. windowes will close the program and notify you if a soultion is available." after i press the button "close program" the progress bar says finnished... and it goes on to the next module, only to stop again on the next module and the same thing happens.... the msg boxes also dont go away unless i close autopatch through the task manager. CAN ANYONE HELP? i'm scared to restart my computer.

Hi

I'm not near a Vista system at the moment, so I can only give you half an answer.

The files you mention are all part of Vista itself. When AutoPatcher requests that a Microsoft update be installed (an .msu file) this is done with:

wusa.exe -- Windows Update Stand-alone Installer (part of Vista)
pkgmgr.exe -- Package Manager (part of Vista)
dpx.dll -- Delta Package Expander (part of Vista)

When AutoPatcher stops with one update, it tries the next.

Many message boxes are appearing, because if AutoPatcher has to install 20 updates (for example) then wusa.exe will be called 20 times and dpx.dll will be called 20 times (or more). So dpx.dll will be "missing" 20 times (or more), wusa.exe will stop 20 times and you will see 40 (or more) messages!

What I don't know at the moment is why dpx.dll is "missing" as this is a Vista system component.

is there a hotfix or a way to reinstall wusa? maybe a way to put a new dpx.dll in the right spot? holla back when you are at a vista station.

I am still unable to determine why dpx.dll has disappeared from your system, although I am sure this is not due to AutoPatcher on its own.

I can only offer general advice on repairing your copy of Vista, which is to run SFC -- the System File Checker. If you do not know about SFC, please read System File Checker (SFC) by Microsoft MVP John Barnett.

Be warned: if SFC finds an error, it will ask for your Vista DVD in order to load the original file. However, if you already have installed SP1 this may not happen (because copies of the SP1 files are already on your hard disk).
