A simple tip for installing software

When you want to install a program, but repeatedly fails in doing the installation, you can try reinstalling the operating system. Probably this means Windows (cause most PC users use Windows. Why should we do so? In normal condition, reinstalling a program usually returning the program to its normal condition.Sometimes, reinstalling needs uninstalling first. When both are done, but the program is still not working, we should do reinstalling on the operating system. This is a simple tip but remember that the data on your harddisk is the most important because it's more painful losing important data than a harddisk damage. So, remember to always backup your data in case some unwanted problem occured when reinstalling cause sometimes you may need to reformat you harddisk for the new installation.
