Second Solution: Check for registry damage

Error 1402 is sometimes caused by registry problem. If you have installed certain programme before and later uninstalled it from your computer, there may be some left over entrys. The system will read these entrys and think that the programme is still there, resulting in failure of the reinstallation.

In such case, you will either use an uninstall manager to remove the left over entries from your pc, or use a registry fixer to clean the registry blocks. After removing these left overs from your computer, the programme will be installed smoothly.
