A small snag was encountered on a setup of a Citrix Metaframe/Xenapp server recently. It was version 4.0 and should have been addressed in subsequent versions (indeed, I've not encountered it in any other version).

The problem was that there no 'Create site' option available in the Access Suite once everything was set up, as well as hitting an error message 'The configuration for the site(s) could not be read'. The error message could have been more elucidating to say the least and it took a lot of work tracking down the problem.

The solution involves the following:

Navigate to System32 within windows and create a file called 'mmc.exe.config'. Open this with notepad (or whatever your favourite text editor) and enter:

<?xml version = "1.0"?>
<configuration>
<startup>
<requiredRuntime version="v1.1.4322"/>
<supportedRuntime version="v1.1.4322"/>
</startup>
</configuration>

This will force the use of .net v1.1.4322, eliminating the problem completely (in theory at least). However, if you still encounter problems, a more definite method would be to downgrade the installed version of .net.
