Aptana 3.6.0 jre Error in Windows os

Prefix the system PATH variable in the studio3.bat file with the JRE 32bit path and launch the program using the batch file.

set PATH=%PRGF86%\Java\jre1.8.0_25;%PRGF86%\Java\jre1.8.0_25\bin;%PATH%;

That way you won't interfere with your other 64 applications.

To pin the batch file to the taskbar, create a short cut for the file and add cmd.exe /C at the beginning of its target properties.

Install the 32-bit java as well and that should clear your issue. Although its x64 compatible it does not like to find the x64 Java. Even if you link it to your correct java you get the ini error. Weird but it works.
