Running onsite security testing with Java JRE, for Gen 8.5 and 8.6, Which version of the JRE is needed with Gen 8.5/8.6 32-Bit or 64-Bit?
Release: KGNDDL99000-8.6-Gen-DBP Developer License
With Gen r8.6, we deliver the 32-Bit version of the JRE with the product (C:\Program Files (x86)\CA\SharedComponents\JRE\1.8.0_60).
In the Gen release notes, we state that "...Although the Build Tool will function with a 64-bit JRE, Gen Studio and Diagram Trace Utility need a 32 bit JRE..."
So, the reason the 32-Bit version of the JRE is delivered is that it will be compatible with all these Gen components. Technically, you can run with the 64-Bit version for the Build Tool.
