Hello,

I take the default install, and have permanent crash with readonly db because they are in the system disk
I am running SQL 2008R2, could it be the reason ?

Database 'C:\PROGRAM FILES (X86)\TELERIK\RADCONTROLS FOR ASP.NET AJAX Q3 2010\LIVE DEMOS\APP_DATA\NORTHWIND.MDF' cannot be upgraded because it is read-only or has read-only files. Make the database or files writeable, and rerun recovery.
An attempt to attach an auto-named database for file C:\Program Files (x86)\Telerik\RadControls for ASP.NET AJAX Q3 2010\Live Demos\App_Data\Northwind.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.

What to do ?
I would appreciate not being forced to de/reinstall, why this read only attribute ?

Thanks
CS

Hi Christian,

I just checked to verify that demo database file is not read-only.
I believe this is a result of the file being locked for some reason, as SQLServer 2008 R2 basically should work normally

Can you load the demos in Visual Studio and try running the project? Does the error happen again? Can you check the Server bar (typically placed near the Toolbox)? Does it have the Northwind database attached?

Kind regards,
