I have just upgraded from 6.2.7 to 7.1.2 but the File Manager under admin and host is invisible. I have tried to install the Document Manager but I get the following error:

Any ideas?

Abot your file Manager issue have try a IIS reset or System reboot?
- Yes, I have but no luck.
Also check your Skin and custom modules for compatibility with DNN 7.1 that comes with new jQuery and jQueryUI library.
- I have applied 2 default skins but I had the same results.
Are you running the database on SQL 2008 (100) or higher mode or is it still on SQL 2005?
- I'm using SQL Server 2008 R2
Have you changed the application pool to use .NET 4.x on 64Bit mode only ?
- I'm using Integrated .NET v4.0.30319
Did you try to install the last or old Version of DNN Documents?
- I have tried to upgrade to the latest version of DNN Documents.
Did your database use an other databaseOwner else dbo and/or an objectQualifier ?
- No

Thanks
