Open up a command prompt, and type:

msiexec /regserver

Reboot, and see if the Microsoft Installer engine works. If not, you should probably run sfc /scannow, then run the above command, to see if that works. Otherwise, you should consider doing a repair installation (as a last resort).

Windows Installer is a service just like many other services that XP uses.

You can find it by running Services.msc from your RUN box.

Make the resulting window a full screen and then scroll down to "Windows Installer".

To the right of the name is a column that tells you the status of the program.

It should say Automatic or Manual. It it says Disabled, that's your problem.

You would have to right click the name, then click Properties and change the word disabled to manual or automatic. Then apply your change and reboot your PC.

Installer should then work.

Good Luck

Try this VBS script it checks to see if the installer service is started if not then it turns it on.

Save As ChkMsiService.vbs, or use the attached SFX file to run the script.

''' Script By Gunsmokingman
 Dim  SD, VBS, Act : Set Act = CreateObject("Wscript.Shell")
 strComputer = Act.ExpandEnvironmentStrings("%ComputerName%") 
  SD = Act.ExpandEnvironmentStrings("%Systemdrive%")
  VBS = SD & "\ChkMsiService.vbs"
  Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\"  & strComputer & "\root\cimv2")
  Set colItems = objWMIService.ExecQuery("SELECT * FROM Win32_Service",,48) 
   For Each objItem in colItems 
   If  objItem.Name = "MSIServer" Then
   If  objItem.State = "Stopped" Then
	Set colListOfServices = objWMIService.ExecQuery("Select * from Win32_Service Where Name ='MSIServer'")
	For Each objService in colListOfServices
	objService.StartService()
	Act.Popup "Starting The Msi Installer Service",3,"Start Msi", 0 + 32
	Next
	Else 
	Act.Popup "The Msi Service Was Running",3,"Msi Was Started", 0 + 32
	End If 
   End If 
  Next
  Dim Fso : Set Fso = CreateObject("Scripting.FileSystemObject")
  If Fso.FileExists(VBS) Then : Fso.DeleteFile(VBS) : End If

Google a program called Dial-A-Fix, it has an option to re-register the Windows Installer Service. Should fix it.

Figured I would put in my 2 cents.. I had a problem with this a few months ago and none of the normal stuff worked.. later found that SYSTEM needs full control access to the c:\ drive and permissions on HKEY_CLASSES_ROOT in the registey needs SYSTEM full control access

[cluberti]

chilifrei64 is right - these permissions should be configured by default, but if you modify them, things will break.
