    Default PDI starting ... Unrecognized option: Xmx1024M

    Hello all,

    I'm not able to start Spoon.bat
    I did the log test and the result is the following.
    Unfortunately I'm not a technician and I got difficult to interpret it . Many thanks

    if you changed anything on your spoon.bat manually than open it again. You have multiple options in that file one should look similar to this:
    if "%PENTAHO_DI_JAVA_OPTIONS% "==""set PENTAHO_DI_JAVA_OPTIONS="-Xms1024m" "-Xmx4096m" "-XX:MaxPermSize=512m" for me this is line 94 in the .bat file btw. I hope this helps.

    The switch character (-) is missing - it must be -Xmx1024m.
    Check your environment variables.
    So long, and thanks for all the fish.
