Can you try upgrading to Emscripten 1.22.0? I think that has improved the
error message for that particular error. For example, when I run 'emcmake
a_dummy_file.txt', I get the following error:
ERROR root: Exception thrown when invoking Popen in configure with args:
"a_dummy_file.txt"!
Traceback (most recent call last):
File "C:\Projects\emsdk_uqm\emscripten\incoming\emconfigure", line 24, in
<module>
shared.Building.configure(sys.argv[1:])
File "C:\Projects\emsdk_uqm\emscripten\incoming\tools\shared.py", line
1048, in configure
process = Popen(args, stdout=stdout, stderr=stderr, env=env)
File "C:\Projects\emsdk_uqm\python\2.7.5.3_64bit\lib\subprocess.py", line
711, in __init__
errread, errwrite)
File "C:\Projects\emsdk_uqm\python\2.7.5.3_64bit\lib\subprocess.py", line
948, in _execute_child

WindowsError: [Error 193] %1 is not a valid Win32 application
The key is that the very first ERROR message lets you debug what it is it's
trying to run.
Also, try just typing 'cmake'. Does that print you the cmake help line with
version information? If not, can you double-check the installation of
cmake, and make sure it is set in PATH?
