Windows Installer won't load

[aileen]

Whenever I try to install a program then I get an error message that says cannot start windows installer. I have downloaded the Windows Installer 3.2 and installed it, but getting the same error. I am running Windows XP SP1. I have tried uninstalling msievec /regserver and reinstalling, which didnt help as well. I tried to do the same in Safe Mode but that still didnt work. Please help.

Did you try to start the Windows Installer Service manually and checked what happens, do you get any error messages? You can try to click on Start > Run and then type Services.msc. After that in the right side, right click on Windows Installer and then click Start. Also try to set the service "Startup Type" to manual.

I have checked that Windows Installer is set to Manual. When I start the service then I am getting error message: "Could not start Windows Installer service on local computer. Error 997: overlapped I/O operation is in progress".

If I am trying to re-register Windows Installer then I am getting an error message that says "An event was unable to invoke any of the subscribers". Please help.

Have you tried to follow the Method 2 given in the above link to reinstall the Windows Installer. Incases you know about Depends.exe tool, then you can use it to determine if this error is due to a missing/corrupt dependancy module. In Dependency Walker, use the "profiling" option and run the command (msiexec.exe /regserver).
