When installing Adobe Illustrator CS6, the Installer says "Your installation encountered errors" but error summary file lists 0 fatal errors, 0 errors, 0 warnings.

Sure! Here it is:

"Installation Failed

Your installation encountered errors.

The error summary file may help you identify the issue.

More troubleshooting tips:

1. Restart your computer.

2. Exit all applications including startup items, virus checking and firewall software.

3. Close this window and launch the installer again to reinstall your application.

If the problems persist, please contact Customer Support for further assistance."

I tried all three of the tips suggested in the troubleshooting.

The error summary file says:

"

Exit Code: 20
