I got the same error, but was on a 64-bit version of Windows 10, Aptana 3.6.1, with only 64-bit JDKs.
After I downloaded the 32-bit 1.7 JDK, I was able to open and start Aptana normally.

I did not need to modify the .ini file, as suggested by AbuSitta.
I agree that this may be misleading for some if you do not take a more keen look and look at the description of "x86, x64" on the download page.
