Hi all,

I have following problem: When editing the content of the Html module after a fresh install 7.4.2 in my dev environment (Win 8.1, , SqlServer 2008 R2 express) the exception shown at the end raises. When installing 7.4.2 in the test environment (Win 2K8 64bit, SqlServer 2008 R2 express) editing the module is without an error and all works fine.

Installing was done using an empty database, modifying web.config to point to this database and calling http://dnndev.me/install/install.aspx. The web site has its own application pool and the application pool user has been granted the necessary rights to the installation folder(s). BTW: This procedure has been used successful (with modifications) beginning with DNN v4.

A google search did not show to much results. What I tried was to clear the "v4.0.30319\Temporary ASP.NET Files" folder - no success.

Does anyone has an idea what the reason for this error can be?

Thanks for your ideas,
Robert

In my understanding the web.config of a web application inherits settings from the machine config which is unique per CLR. The application web.config defines settings at its own level - but I am really not the expert with that configurations.

The .net temp file cache I deleted before as described in the initial message.

There are existing older website versions on my dev machine - and with the above given logic the version 7.4.2 has to run as all the older ones.

This said I repeated the installation of a 7.3.4, 7.4.1 and 7.4.2 with its own hostnames - with success!

Then I got the idea, that an existing website (dnndev.me) which had been running with different versions - please note, that the application pool was a new one - could be the problem. I deleted that website (dnndev.me), deleted the application pool an created new ones and repeated the installation procedure - success!

Conclusion: Performing a New Install should include creating a New application.

p.s. If somebody has the detailed explanation (like: the application configuration had been stored in the folderAAA\fileBBB and will be reused until you recreate the application - or something other) - I do really appreciate this.

Best regards
Robert

Cathal,

I took your comment to reread the config documentation in http://www.iis.net/learn/get-started/planning-your-iis-architecture/the-configuration-system-in-iis-7.

Here I mentioned the applicationHost.config - this is in my understanding the only point which can change when deleting and creating an application. 

Whith this in mind I restored an older applicationHost.config and compared this one with the current file.

Here I found the root cause: there was an additional entry <virtualDirectory> which pointed to a full qualified path of an other (older) version. This resulted in a mixed compilation of two different versions.

Thanks to all
Robert
