Error code 641 and code 80070641?

Hi,

   I use Vista Business Service Pack 2.  I also use System Mechanic Pro for registry cleaning and other repairs.  Sorry, not sure which green button I needed to unmark-can you let me know?

 

Thanks!

The very topmost one.  Assuming you had marked Answer before, then click the UNMARK green icon to clear it (first).

Windows update exception code 0x00000641 / 0x80070641 usually indicates an issue with the Windows Installer service.

Sometimes it is due to a difficulty in accessing it; sometimes it means it's missing, or inactive (disabled) for some reason.

If you have used Iolo System Mechanic for automated (auto-fix) runs, and have these exception codes, the cause is an overagressive fix by this app.

First suggestion is to Undo recent fixes by S M, then insure it's not set to autorun or autofix.

Do NOT keep using System Mechanic until there is a permanent fix from Iolo.

Contact Iolo support (iolo.com)

and demand a permanent fix.

System Mechanic "registry cleaning" has put a double whammy on your system in having removed two registry keys.

The following will put things back in order for the registry {at least for the Installer service}, so that you can then proceed to redo Windows Update.

This are for VISTA systems <<<---

Download this file from Ramesh S http://www.winhelponline.com/fileasso/regfix\_vista.zip

Save it to your DESKTOP.

EXtract the contents to your DESKTOP.

go to Start, type in

REGEDIT and press Enter-key

from main menu, select File

then select IMPORT

navigate the dialog (click on DESKTOP icon on left to select it)

type in regfix_vista.reg in the Filename text-box and click Open button.

Once the merge is complete, you will see a confirmation message.

Click OK when done.

Next, get this second registry-fix

Download and SAVE to your system (to the Desktop or a unique folder) the following registry-fix file

IF and ".reg" file pops up in REGEDIT, when prompted whether to Merge answer Yes.

When done with the two registry fixes, Exit / close REGEDIT.
