http://www.asg.com/images/emailref/Kentico-Upgrade-40-to-41-error-sreenshot.jpg This is on a system that was successfully upgraded from 3.1a to 4.0. It also occurs with or without the .Net 3.5 assemblies. Any ideas? Dave

Hi, We too have upgraded from 5.0 to 5.5 and we have the same problem. We haven't done any customization. Thanks

Hi, Visual studio should convert the web project to .Net 4.0 in the same way as it was 2.0 -> 3.5 version. You may need to alter the web.config file after the conversion and update the version references. Best regards, Juraj Ondrus

Hi, My fault. Regrettably this key was added into 5.5 version so it won't work in 5.0 version. You will need to upgrade to achieve this functionality. I am sorry for the confusion. Best regards, Juraj Ondrus

Hi, Which version of SQL server do you use? Could you please send us whole error message you are getting? Thank you. Best regards, Juraj Ondrus

How does one run the Update_5_0_to_5_5.sql file when using SQL Express? The Management Studio 2008 Express does not seem to run .SQL files.

Hi Nick, What version do you use? Could you please upgrade to the 5.5 version with the latest hotfix? (Hotfixes) Please let me know if it helps. Best regards, Helena Grulichova

Hi, I think I was in touch with you or your colleague with the same issue. In the ticket was mentioned that you will try the upgrade to 4.1 and hotfixes - but haven't heard back from you. Are you still experiencing this issue? Best regards, Juraj Ondrus
