What does the error "Corrupt Installation" Mean?

"Corrupt installation detected" usually
means:
-the file did not download properly, maybe because it was interrupted.
-your disk is full
-your Windows system directory is write-protected
-you do not have admin rights

Clear your browser cache and try again.
Download the file and save it. Look at its Properties. The size should be approximately 5.3MB. If the file is much smaller than this than it's corrupt.
-Make sure you are free of viruses.
-Run Scandisk.
-Make sure your C:\ drive is not full.

If this problem persists, email me. Tell me:
-your system details (PC, OS, internet connection etc.)
-your Browser version
-the results of checking the above suggestions.
