Hello, I have the same problem.
If I execute openHAB-Designer.exe I get the following error:
“Java was started but returned exit code=13”
It is using “C:\ProgramData\Oracle\java\javapath\javaw.exe” that it is pointing to a 64bit java installation.
After that, I installed a 32bit java. Now, I need to config the openHAB-Designer.ini to indicate the 32bit java due to I need to keep the default 64bit java.
If I put “-vm C:\Program Files (x86)\Java\jdk1.8.0_66\bin\javaw.exe” before -vmargs it gives me the same error and if I put the -vm command after the -vmargs it gives me an exit code=1.
How could I solve this problem? Using -vm alwayis worked for me in other eclipse installations.
Thank you.
