Asp.net published web site: The specified module could not be found. Exception from HRESULT: 0x8007007E

Question

Hi,

I'm having a problem when browsing a published site on local iis7 (on windows 7).

When browsing the asp.net site through VS2008 with F5 (dev iis) it works fine. When publishing it and browsing, I get a:

Server Error in '/MySite' Application.

The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IO.FileNotFoundException: The specified module could not be found. (Exception from HRESULT: 0x8007007E)

Stack trace offers no clue on the problematic dll either. I copied the same published folder to a different machine (also with windows 7 32bit and iis 7) and it works.

Since this is a fresh install of iis on my machine, I verified the matching selected items in "Turn Windows Features on/off". After noticing the issue I also ran the "aspnet_regiis" util, but the problem remains.

The web site includes several external dlls (native and managed) and they all appear in the published bin folder (which is identical to the development bin folder)

Any insights?

Cheers,

Shay

Native dlls are supposed to be locatable in the PATH. Problem was they were under the User PATH and not the System PATH, so it worked fine through the VS but not through the IIS. I added the dll folder to the system PATH and everything worked...
