I have two version on my server. Remember it :D
**************************
When multiple versions of the .NET Framework [v2.0 and v1.x] are installed on your server that use IIS 6.0, you might encounter following error message in the Application Event log and v1.x enabled websites may go down.
"It is not possible to run different versions of ASP.NET in the same IIS process.
Please use the IIS Administration Tool to reconfigure your server to run the application in a separate process."
According to Microsoft these different .NET Framework versions cannot coexist side by side within the same shared Application Pool. After applying hotfix you will be able to run all .NET enabled websites with their associated .NET versions without any problem. Now HC will create and set DefaultAppPool1.4 for v1.x enabled websites and v2.0 enabled websites will run under DefaultAppPool.
To set DefaultAppPool1.4 for all existing v1.x enabled websites we have provided interface to change Application Pool. You have to simply click on "Set App Pool" button right in front of every website to change its Application Pool and it will get removed from this list as well. If you have any query then please send mail to
support@hostingcontroller.com.

If Version 7 is development in .NET 1.41 then this used the DefaultAppPool1.4 or other isoletd AppPoll, right?
