Where previously there were both 32-bit and 64-bit versions of the QlikView software, QlikView 12 desktop and server are only available in the 64-bit version. The 32-bit QlikView desktop version, with its memory limited to 2 GB, has become outdated. If you have a hard requirement to still use a 32-bit version of the software, you will need to fall back to QlikView 11.2.
