Title: Windows Installer Service could not be accessed
Post by: Shelly300 on June 25, 2013, 05:32:51 am
I'm having trouble with the Windows Installer Service on Windows 7 Ultimate.
Was able to install MalwareBytes, CCleaner and various other programs but am unable to install XLite, Adobe Reader, AVG, and others.
The message I get is: The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. That message was delivered by Adobe but the message is similar from one and all.

Things I have done already include:
None of the above has helped.

I couldn't find a .msu for Windows 7; all I get is service pack 1 which is already installed.

I ran sfc /scannow. I did this early in the piece and did it again after all the above with the same results. It said: Windows Resource Protection found corrupt files but was unable to fix some of them.
Details are included in the CBS.Log windir\Logs\CBS\CBS.log.

A search of the CBS.log file showed a number of errors that I have no idea what to do about.

Here are all the errors the scan identified:


Is there any advice you can give me that doesn't involve a re-install of the OS?

Kind regards

The Service is used by the Windows installer technology. Some programs use this technology and other don't.

1. Install the latest version of Registry Backup (v1.61) and make sure it makes a copy of the registry once a day. It's also in a subfolder of where Windows Repair is installed. The Services are registered in the registry.
2. Did you run WR's reset file & reset registry permissions ?
3. Did you run WR's "Restore Important Services to default" ?

Windows installer is MSI and I have a repair for that in my Windows repair tool, have you tried it yet?

Thanks for your replies.

Willy2, on point 1, I have used CCleaner to do a registery backup but, as the problem is already in place, a backup can't help me now. On point's 2 and 3, yes I did.

Shane, yes I did.

I used WR tools... all of them. I did everything as instructed by your software as well as crossing my fingers and toes during the process. Your software seems like a great tool that has worked wonders for many but it said something about commenting on the forum if my problem wasn't fixed. I don't want to be the someone with the unsolved problem but here I am.

In the CBS log errors there is something called the 'localized custom property bag' - see the fifth error I have listed. I have no idea what this is but if it's missing and it's supposed to be there shouldn't I try and replace the missing something?

Lots of unknown errors in the log you posted. When sfc is messing up you know there is a problem that is deep.

The best thing to do would be a repair install, which would keep all your programs and settings and just get Windows reinstalled.

To do that you need a Windows 7 cd with SP1 already on it, you can grab that here

Then follow this guide :wink:

I will do what you have advised. It sounds like the best option.

Kind regards

Shane, there are several issues with this problem; I would only do a repair install too...

The other way is to create a new CBS store, it usually still does not fix any problems and reports the same errors.

could run sysinternals to see a report too to compare system files related to the missing errors.

Best solution, do a repair install
