I got this Unhandled Exception below while launching the Xamarin Android Player as an administrator on my machine.

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:

<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.

I have been unable to replicate this on the latest version in Windows 10 x64 and Windows 7x64.

Is this still an issue? If so, can you please attach logs to this post. 

If you right click on the lower black bar of the Device Manager window and select 'Generate Bug Report' then XAP will collate a selection of relevant logs and place them on the desktop in a zip archive.
Comment 2 Will Schaller 2015-07-28 04:30:22 UTC
We're closing this since our assumption is that it's been fixed in a recent release. If it's still an issue, please re-open and supply logs so that we can investigate. Thanks.
