System Workbench for STM32

I have a similar issue: something in the PATH that is incompatible. In my case, git was causing problems. Rather than change project settings, I start Eclipse in a .bat file with a simplified PATH variable - something like this:

set PATH=C:\ProgramData\Oracle\Java\javapath;C:\Windows\system32;
C:\Ac6\SystemWorkbench\eclipse.exe
