Got the same problem

Tryed to upgrade my 4.8.0 portal to 4.8.2, failed badly
Stucked at the :

Installing Database - Version 4.4.0...Upgrading Database to Version ERROR: See D:\Inetpub\vhosts\bigwar.org\httpdocs\Providers\DataProviders\SqlDataProvider\04.04.00.log for more information...FAILURE 400 - Conversion from string "ERROR: See D:Inetpubvhostsigwar" to type 'Integer' is not valid.

I'm a newbie with DNN I admit, but I seem to be getting the same problem as everyone else.  I downloaded DNN and then opned it using the VS wizard.  The template was in the MS visual web developer and I began following the instructions for putting up a file based site.  I check all the permissions indicated by the book and on screen instructions.  But like everyone else, it seems to stop (and loop) at the database installation.  I've let it run for 24 hours with no luck.  And it start throwing javascript errors.  Any help would be appreciated.  Help!!!

Hello There,

I am trying to install DNN455 on my new webhost. I think I got the same error as everyone here:

Installing Database - Version 4.4.0...Upgrading Database to Version ERROR: See C:\Inetpub\vhosts\mywebsite.co.il\httpdocs\Providers\DataProviders\SqlDataProvider\04.04.00.log for more information...FAILURE 400 - Conversion from string "ERROR: See C:Inetpubvhosts orexi" to type 'Integer' is not valid.

I didn't see this error on my old webhost. The difference between the 2 hosts is the MSSQL version.
In my old host I use MSSQL Server and the new one MSSQL Express Server.

After I got the error, I got out of my website. When I tried to call my website again I got the MSSQL versions upgrade. When it ended successfully, it instructed me to go to my site. I opened my website and got another error:

Domain Name www.mydomainname.co.il Does Not Exist In The Database

DotNetNuke supports multiple portals from a single database/codebase. It accomplishes this by converting the URL of the client browser Request to a valid PortalID in the Portals database table. The following steps describe the process:

1. Web Server Processing
   
   • When a web server receives a Request from a client browser, it compares the file name extension on the target URL resource to its Application Extension Mappings defined in IIS.
   • Based on the corresponding match, IIS then sends the Request to the defined Executable Path ( aspnet_asapi.dll in the case of ASP.NET Requests ).
   • The aspnet_isapi.dll engine processes the Request in an ordered series of events beginning with Application_BeginRequest.
2. HttpModule.URLRewrite OnBeginRequest ( UrlRewriteModule.vb )
   
   • The Request URL is parsed based on the "/" character
   • A Domain Name is constructed using each of the relevant parsed URL segments.

and so on...

Can someone official help here?
