Crash on startup if write access is denied to the IE browser emulation registry key

Description

mRemoteNG tries to set a registry value in HKCU\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION\mRemoteNG.exe which results in an Access Denied on my computer. The computer is in a domain and access to that registry key in denied by policy. I understand this affects the functionality of the browser emulation but now I get an error message and when I click "Continue" the mRemoteNG process just hangs without showing a user interface. I was using a previous version fine on this computer though. Can you change the code to check for access and continue on failure leaving the IE browser emulation disabled?

The exact error message is: "Unhandled exception has occured in your application. If you click continue. the appliction will ignore this errror and attempt to continue. If you click Quit. the application will close immediately. Attempted to perform an unauthorized operation.".

Details:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

- - - - 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:

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.
