2всем, у кого глючит инсталятор

Why is the error message "The setup files are corrupted" displayed on some systems?

This error message is displayed when a file pertaining to the installation (e.g., setup.exe, setup.1) has the wrong size, or part of a file fails a CRC check. It is not displayed for any other reason.

If your installation is distributed over the internet and you're getting a lot of reports of this error, it could be that your web server is delivering partial files by dropping connections prematurely. Have the affected users check the size in the bytes of the file(s) they downloaded.

Так что проверьте размер скачаного файла.
