So here's my target line

C:\ProgramData\Oracle\Java\javapath\javaw.exe -jar -DTW.install.path="C:\Program Files (x86)\GOG Galaxy\games\The Witcher Enhanced Edition\launcher" -jar TWEditor.jar -Xmx256m

The javaw and launcher locations are correct but when I try to open the thing nothing happens!
there is something wrong?

If you interested in a wild guess, I've never used Galaxy, but it might be that the javaw.exe is denied access to the protected C:\Program Files (x86) directory.

So I noticed that this file called "hs_err_pid1292" was created, Containing a error mensage
