Hi, I want to switch to a different Antivirus because COMODO Internet Security asks if I should allow EVERY connection with the outside world, which, as you can imagine, has become very annoying. However, when I go to Add/Remove Programs in Control Panel, and select "Remove" for COMODO, the following Error appears:

"The Windows Installer Service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed. Contact your support personnel for assistance."

Well, you guys are my support personnel, and I'm definitely not in Safe Mode (though I have tried going into safe mode and running "msiexec /regserver"). I've tried removing other programs and none of them work, so it's not just COMODO.

I must add that this all started after I installed and ran CCleaner, so perhaps it *accidentally* removed a particular Registry file?

Did you see if the service of the windows installer is set to manual or automatic. To check its setting from the start button type in the command in the run box
"services.msc" without quotes. Scroll down to windows installer. Should be set to manual or automatic. If it is already set to automatic it should say under status heading "started" If set to manual will start on it own when the service is needed. If it is not currently running to see if it starts up with no trouble right click on it and select start. Does it startup with no errors? It should remain on till you manually stop it or reboot. If it won't run then download Windows Installer 4.5 Scoll down to the lower part of the page and download WindowsXP-KB942288-v3-x86.exe Hopfully that will fix your windows installer right up.

*cries*

I've looked all over the web for a solution. This was the first thing that I tried.

It was set to Manual before, but I changed it to Automatic. Yes, it starts up fine. I've even tried restarting it. I tried installing Windows Installer 4.5, but there is no confirmation message when the installer "finishes". Isn't it supposed to appear in the Add/Remove Programs list?

PS: Thanks for the quick reply.

Just tried the update myself from windows installer 3.1. It asked for a reboot on my system after installing 4.5. Under add/remover program it shows up as "Hotfix for windows xp(KB942288-v3). Make sure that the show updates box is checked. Another thing to look at is in your folder options, file types tab. Scroll down to msi then advanced button. On mine under actions it has install, uninstall, repair. Confirm open after download box is checked. If same click cancel. Click change button. Box popup with it saying under recommend programs "windows installer". Always use the selected program to open this kind of file box is checked. Did you try these step found here to repair windows installer: http://wiki.williams.edu/display/do...
Their link to the lastest version is an old version. Just try installing 4.5 again.

Method 1 didn't work (I've tried it twice before) so I tried Method two.

At the point where you rename "msi.dll" to "msi.old", it says it cannot find the file specified.

WTQ??!

EDIT: Also, despite the installer for WI 4.5 completing, it did not ask me to restart, nor did the Hotfix appear in A/R Programs. So, apparently I can neither install nor uninstall any software whatsoever.

If worst comes to worst, I wouldn't mind "Repairing" XP with the command line on the disk, since I can just back up my files to my Ubuntu Linux partition.

EDIT 2: Thank God for System Restore! It was the CCleaner scan that caused all this mayhem! I went back to a point before I did the scan, when I installed the Microsoft Zune software for my sister's Zune. Now Windows Installer works, and I installed a new antivirus (Avira AntiVir Personal) successfully. I was wondering about that. So does this mean CCleaner, a very reputable program, is malicious?

I am also have this problem over years. Before,I do not want to resolve this problem because I am kind of of scarry, may be valuable other folders, files , phootos and etc will be gone, even all my Xp window operating systems!!!. I do know I can backup everything including operating systems then I can start startup the trobleshoot, if I can backed-up properly all the files and folders.Even anything goes wrong my belongs will be safe.

Please any one let me any suggestions how would I back-up within same system with the help of partitions application instead of using any high memory usb sticks which is physically different than system of mine and need to do more works?
Thank you
