Hi all

We got a strange error installing a clean hglab environment. Setup was running as expected. browsing to the site gives us an 500.19 error on a specific error message:

Config Error: The configuration section 'system.runtime.caching' cannot be read because it is missing a section declaration
Config File: \?\C:\Program Files (x86)\HgLab HQ\HgLab\web.config

I have checked the web.config several times (also the ACL), seems to be ok.

Thank you

    Could you please double-check that .NET 4.0 is registered in IIS and that the Application Pool is configured to use ASP.NET 4.0.

    problem: i added the application pool as "default" and changed the .Net version later to v.4.0. this did not work (see attachment)

    solution: add the application pool as " 4.0" - works as expected!

    thanks for the hint.

    You probably had to recycle either the Application Pool or the Web Site for changes in "Default" to take effect, but having a separate pool for HgLab is a better option.

    Glad you got that fixed!
