Windows Xp Installation Error

[Sabastiaan]

I was trying to install a program on my Windows XP operating system, but windows is giving me a error message saying,"Another installation is already in progress. Complete that installation before proceeding with this install". I rebooted my system and tried again but still the error message occurs. Why is that so ? Please help.

This issue occurs because Microsoft Windows Installer can only run one installation at a time unless it is a nested installation.To prevent a second instance of the Windows Installer, do not repackage a Windows Installer package into another Windows Installer package such as a custom .msi file. Office updating and upgrading will not work with nested installations with the current version of the Windows Installer.

All Office public updates include a bootstrapping program that is named OHotfix. While OHotfix is not the only tool that you can use to deploy updates, it is the easiest to use because it provides a lot of the necessary updating functionality.

You can also use other updating bootstrapping programs, such as a simple batch file or a complex custom program that uses the Windows Installer API calls.

Just go to Start menu and click on Run. Type services.msc in the command and press Enter.Now on the right side Scroll down to the Windows Installer service and double click on it. here Stop the service and restart your computer. Thats it.. Hope now error won't pop up.
