Windows Installer Problems

Hewlett-packard / Hp pavilion dv4 notebook...

Specs: Windows Vista, 2 GHz / 3998 MB

I am currently experiencing an error message regarding Windows Installer each time I try to download an update (most recently iTunes 10.1 update or AVG 2011 update).

I am using an HP laptop, running Windows Vista, and in the 3 years since having the computer I have never had any problems with this.

The error message I keep receiving is:
The Windows Installer could not be accessed. This can occur if you are running Windows in Safe Mode, or if the Windows Installer is not correctly installed.

I have researched this on Microsoft forums in an attempt to solve this myself, but after confirming that I have the latest Windows Installer version (4.5) and confirming that it is not disabled, I am at a loss of what to do next and how to rectify this.

The main problem is that I cannot use my iPhone now without the iTunes update, so if there is ANY assistance/advice anyone can share with me, I would so genuinely grateful.

Many thanks,

Hi Amy,
I just walked in, went to town for a bit.
I just worked on a problem like that in my shop.
Look in your add/remove and see if you have the windows installer in the list or something pertaining to that pop-up you are getting.
:Let me know if it is and what it is called.

Hi XP,

Thanks for your reply.

I'm not sure where the add/remove is on my computer, so I opened up my Control Panel and then went to 'Programs/Features' which then opened up a file with all of the Programs and has the "uninstall, change, repair" option. I then searched for the Windows Installler, but it came up with nothing.

Then, per instructions online, I went to Start, searched 'cmd' and entered MSIExec in the Command Prompt.
A box popped up with all of the Windows Installer information, I have pasted it at the bottom of this email.
I also went to Start and typed in 'services.msc' and in the services prompt I found the Windows Installer programs and determined that the Windows Installer was not disabled, but is in the Manual mode and has also been "started."

What else should I do?

Many thanks,

hmmmm, another thing I did was download malwarebytes
to your desktop. Then reboot and tap f8....go to safemode with networking. Install it and let it download nay updates and then run a full scan, remove all it finds and then reboot to normal mode.
See if that helps
