If the double click caused two processes to be started on the host, this
approach will probably not work.

A workaround could be to start a script (batch file) such as

if exist abc.tct goto END
echo busy>abc.txt
whatever.exe -a -b -c
del abc.txt
:END

Not very elegant, but will probably solve your problem.
