Could someone point me in the right direction, I am assuming I have missed a config somehwere or something is not installed correctly?

Cheers,

Tahir

Any comments on this issue? I'm experiencing the same.

Hello,

To setup the eduction starter kit up and running go to App_Data/Sitefinity/Configuration folder and move the existing configuration to another folder so Configuration folder gets empty. Run the site in browser and you will be prompted to connect to database and setup and admin user.
This will create new database for the starter kit with all the content and templates installed.
After running the site add SocialShareConfig.config back in the Configuration folder as well as the ResourcesConfig.config. Restart the application and the multilingual data will be installed for the site.

I haven't encountered this problem, yet.

Hi Stanislav,
I have the same problem - the Education sample gives an SQL error.
I followed your instructions:
- and I also deleted the database which, I assume is what you implied by saying "this will create a new database"
Unfortunately after pressing the "I'm Done" button, I get the error message :
"The specified role "Administrators" already exists." (See attached file)

 I'm new to Sitefinity (this is day three of my trial).
My past ASP.NET projects have all used role management systems that are stored  within the database. However, I remember reading somewhere that Sitefinity uses an XML based role management system which, if that's true, is what is probably causing the error.

How can I work-around this error?

Thanks
Ken
 

And of course since I deleted the database and did not create a backup,(silly me!)  the default site is now kaput!
Do I have to re-install the whole thing?
Ken

Hello,

I would advise you to re-install the application. Delete the created base from Management Studio. When you "Run sample in browser" Sitefinity SDK Browser attaches the database and sets the entire project (connection strings etc.)
I`ve recorded a short video how to set a Sitefinity SDK Project video

Hi Vassil,
Thanks for your message.
Please clarify what I have to uninstall. Is it everything?
See the attached files:
* There are four databases.
* There are three lines beneath Sitefinity 6.1
Are you saying that I should uninstall everything?

Thanks
Ken

Hello Ken,

The easiest and harmless way to deal with this is to purge all data using this button in Sitefinity SDK Browser. It will delete your database which is causing troubles and also your Education Sample.
Then click on "Run sample in browser" and I believe this will solve the problem.
