Remote debugging monitor does not appear to be running on the remote computer error but I am not trying to run remote debugger

I am getting an error message,

"The Microsoft remote debugging monitor (MSVSMON.EXE) does not appear to be running on the remote computer."

But I am not trying to run the remote debugging monitor.  If I change the target to X86 the error goes away and the debugger runs fine.  I know MSVSMON.EXE is used even when you are not running remote debugger on 64 bit applications.  Why am I getting this error? I checked my project properties under the debug tab and I don't have Start external project checked.  I don't have Use remote machine checked.  I used to be able to debug this program with it set to Any CPU for the target.  Why do I have to change the target to X86 in order to debug the program?
