Event message: An unhandled access exception has occurred (IIS 7.5, cannot load website)

Question

I deployed the Nuget source code to my company's web server, but when navigate to the URL, I get the following error (pulled from Event Viewer on the server):

This will run just fine on my local machine, but not on the web server. Does anyone have any ideas as to what the problem might be? All I did was take the Nuget source code, modify the database details in the web.config to point to my database, and deploy it to the web server.

Answer 1

The local users group needed modify permissions to get past this error. Resolved.

Answer 2

I would just like to clarify for anyone else who comes to this question. The permissions need to be changed on the folder where the website resides in windows explorer.

Answer 3

I had this exact error - the only solution that worked was setting the app pool's Enable 32-bit Applications advanced setting to True.

Update: As I continue to have issues with a particular solution, I've found that clearing the C:\WINDOWS\Microsoft.NET\Framework\v4.xxx.xx\Temporary ASP.NET Files\ resolves the issue in most cases.
