ASP.Net Configuration File

[Joel Cade]

I'm having a problem with ASP.Net on a machine with both .Net
Framework 1.0 and 1.1. This application is targeted to 1.0 using IIS
application extension mappings. The following error page is shown
when the page is accessed.

Server Error in '/' Application.

Configuration Error
Description: An error occurred during the processing of a
configuration file required to service this request. Please review the
specific error details below and modify your configuration file
appropriately.

Parser Error Message: Execution permission cannot be acquired.

Source Error:

The stack trace in the source of the page states:

....
The following steps have been taken:
- The indexing service has been uninstalled on the server and the
server has been rebooted.
- There is no anti-virus software running on the machine.

I've searched the Microsoft knowledge base and google groups, but
haven't found any answers. Thanks in advance for any help!

Check IIS, as ASP.NET Framework 1.1 maps to 1.1 in IIS when installed. In
your config file, you can add the following, which will make sure 1.0 is
used for this app.

<startup>
<supportedRuntime version="v1.0.3705" /> <!-- version 1.0 -->
</startup>

If this does not straighten it, you have to look at the security profile you
are using for this app. 1.1 locks things down more than 1.0, which is
overall a good thing. It sounds like your app, although you feel it is
configured for 1.0, is running under 1.1.

I have the exact same problem, and it came out of nowhere. Everything
was working fine and then it just broke on me. I was coding and then I
installed Macromedia Shockwave or something to view something on a web
page and kerplam I'm dead in the water. I checked the last modified
stamp on my machine.config file and it doesn't look modified. I didn't
change anything in the security settings myself.

Also, why would you want to change the application to run on the version
1.0 framework instead of 1.1?
