Created a project as per http://www.visualmicro.com/post/2016/01/03/GDB-for-Arduino-INO-Initial-Beta-Note..., which uploads to Zero OK. F5 gives pop-up "Unable to start debugging. Cannot access as disposed object. Object name: 'Debugger'."

To confirm that a program was uploaded, the Blink program lines were copied into this blank program. F5 generates the same error but the new Blink program is running on the Zero.

Neither openOCD.exe or MicroGdb.exe are present in Task Manager.

Switch optimization off for this file makes no difference: 

#if _VM_DEBUG
#pragma GCC optimize ("O0")
#endif

I am using:

Windows7
Arduino.c 1.6.9
VM 1606.17.10
Microsoft Visual Studio Community 2015 Version 14.0.25421.03 Update 3

Using Arduino.cc Zero board, which VM successfully uploads programs to.

I followed the instructions at http://www.visualmicro.com/post/2016/01/03/GDB-for-Arduino-INO-Initial-Beta-Note...

Please provide a link to any other instructions; I have already read http://www.visualmicro.com/page/User-Guide.aspx?doc=Arduino-gdb-In-Brief.html, http://www.visualmicro.com/page/User-Guide.aspx?doc=Arduino-gdb-Differences.html and http://www.visualmicro.com/page/User-Guide.aspx?doc=Arduino-gdb-Tutorial.html

Additional information:

The first time I uploaded the project, it may have stopped at one of the default breakpoints and would not step beyond it. I do not recall checking the Zero to see if the new Blink program with a different flashing sequence was executing.

I went to vMicro.Debugging.Automatic Debugging and turned it off, which may have allowed the breakpoints to be ignored, but I am unsure on this. After4 turning on vMicro.Debugging.Automatic Debugging again the error described occurred.

Sorry for the delay. There is a new release with the update.

It doesn't require the Microsoft linux extension, still requires the android tools to be installed.
