[solved] Revolution Beta 4 install fail

When trying to run the install (after fixing any errors for folder/file permissions) I get the following message:

Installation Summary

Errors were encountered during core installation. Please review the installation results below, correct the problems and proceed as directed.

But the are no errors listed just a "Retry" button... that presents the same error message once clicked.

(my php memory limit is 128mb)

Trying to access /manager afterward just presents a blank page.

fixed.

I had created a default config.inc.php file because it warned me that one did not exist. this time I did not and it installed fine.
