How To Repair Windows Installer

If your computer is always asking about installation source every time you run an application,
for example MS Word, MS Excel, ect.
I have tips to solve this problem by changing some registry on your
computer system, and do not be afraid of doing it because this way you
only need to copy the reply I gave Script below and paste it in notepad
and save with extension ".reg" (for example: fix.reg or repairwinxp.reg, what ever you like).
After that double click .reg file.
