7.6.1 to 8.1 Upgrade Problems

Hi Everyone :)

I tried upgrading from Plesk 7.6.1 to Plesk 8.1.1 and found few errors, the installation then rolled back and now the plesk 7.6.1 is even not accessible.

The errors that I got at the time of installation are as under
----------------------------------
Error 1923. Service 'Sitebuilder for Windows Hosting Service' ( SBPreviewHost) could not be installed. Verify that you have sufficient privileges to install system services.


Error 1720. There is a problem with this Windows Installer package. A script required for the install to complete could
not be run. Contact your support personnel or package vendor.
-----------------------------------

Then after the rollback , I restarted plesk service and other services and even tried rebooting, but now I am getting the following at the Login Page
------------------------
Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0

Warning: Unknown: Failed opening 'auth.php3' for inclusion (include_path='C:\Program Files\SWsoft\Plesk\admin\plib') in Unknown on line 0
-------------------------
Plesk repair also did not work to fix the login page error..

Any idea how to fix it ? or how to upgrade to 8.1.1 ?
