MS .NET Framework jit debugging error

I have been trying to instal ACAD 2008 on a single PC and get the following
Microsoft .NET Framework security error.
I have updated to the latest .NET Framework software.

I also got the same error when trying to instal an old ACAD 2005 version (as
a check).

I have tried changing the acad.exe.config file as mentioned below and have
tried installing with the virus software turned off.
The machine config file is set to default. This has never occurred with any
other software instals.

I have found this error mentioned elsewhere (after a Google search) but have
not seen a solution as yet.

regards

************** JIT Debugging **************

To enable just-in-time (JIT) debugging, the .config file for this

application or computer (machine.config) must have the

jitDebugging value set in the system.windows.forms section.

The application must also be compiled with debugging

enabled.



For example:



<configuration>

<system.windows.forms jitDebugging="true" />

</configuration>



When JIT debugging is enabled, any unhandled exception

will be sent to the JIT debugger registered on the computer

rather than be handled by this dialog box.
