openEMS folder in 'Program Files': openEMS binary exited with error-code 1

[LukasJuchli]

Hi,

as I'm knew to github I don't know if placing the issue here is right. Please redirect me to the correct location if posting it here is not right.
I followed the initial steps (documented in your wiki) using Matlab. When running the following command I got the following error:
Command
RunOpenEMS( '.', 'nonexistant.xml', '' )
Error
"openEMS binary exited with error-code 1"

After some digging it got clear that running the openEMS.exe Matlab failed due to a whitespace ' ' in the path directing to the exe-file. In my case it was 'Program Files' that had the whitespace included. Therefore Matlab was not able to run the exe.
Changing line 37 of 'invoke_openEMS.m' to the following solved the problem.

command = ['"' openEMS_bin '"' ' ' opts];

I don't know if this is the 'best' or 'cleanest' solution, but it worked for me.

Note to first-time users: As mentioned in the Wiki, you'll still get an error. But the error is due to not finding the .xml file which doesn't exist. However, the error-code will have the value -1 and not 1 as in the case of not being able to run the exe-file.

Best regards,
Lukas
