Our recommended installer for both 32-bit and 64-bit Windows machines:
This is an installer that comes packaged with Java 32-bit and works on all machines, 32-bit Windows and 64-bit Windows.
All functions are supported in the recommended installer.
We also publish a 64-bit Windows installer that comes packaged with Java 64 bit.
Limitation of the 64-bit installer
Note that in 64bit, PDF Studio’s Scan-to-PDF function will only show the WIA driver, not the Twain driver. This is because Twain drivers on the market, even those which are labeled as supporting 64-bit Windows, are in 32-bit mode.
