Moving from IIS6 to IIS7 and it won't load

So we have moved our app from .NET version 2.X in IIS6 to a Windows
2008 Server running IIS7.

We have copied all files to the Windwardreports\apps directory and
that apps directory has been converted to an application running in
..NET 2.X and Integrated mode.

We copied over the DB and edited the web.config file to the DB
username and password. I also added the NETWORK SERVICE user to the
DB.

We checked all DLL’s to make sure they are all AnyCpu and they are.

We have added the below registry entry to get more info but none is
given. These are the core DLLs the store is using to run and I think
it just picked Apache.Crimson because it is the first of the 12 that
it needs.

This file does exist in both the store\lib and store\bin directories
so I am not sure why it cannot find it.

The trust level on the apps dir in IIS7 is set to Full Internal so
that should not be an issue.

Any idea why we get the below?

Upon opening the webpage for the first time I always get this error:

More on this - we got it working by doing the following:

1) In the application pools right clicking and then selecting Set
Application Pool Defaults

2) Setting Enable 32-bit Applications to True

The thing is, we have all AnyCpu DLLs - why is this happening?

thanks - dave

Hi Dave,

Regarding on the two changes you've made below:

======================
1) In the application pools right clicking and then selecting Set
Application Pool Defaults

2) Setting Enable 32-bit Applications to True
=======================

I think the 2) should be the critical one. Maybe something in your web
application is specific to 32 bit runtime. For the 'Apache.Crimson" , is it
a pure .net assembly or unmanaged win32 dll. Or does it have any other
depedency assemblies whch is specfici to 32 bit environment?

Sincerely,

Steven Cheng
