Bug #3785
openUnclear Java requirements for Kepler installer on Vista 64-bit
0%
Description
On a Vista 64-bit machine, the Kepler 1.0.0 installer for Windows failed with 64-bit JRE 5.0 (Update 16) installed, reporting the error "Cannot find Java 1.5.0". Adding the correct Java bin directory to the path variable didn't make a difference, nor did running the installer as administrator, nor did running it in compatibility mode for XP.
After I closed the installer error window, a web browser window automatically opened at the Sun download page for (32-bit) Java 6 -- not 1.5.x, as the Kepler documentation suggests. Nevertheless, after I installed this, Kepler installation proceeded normally, and Kepler itself seemed to work (superficially at least). Subsequent experimentation indicated that installing 32-bit Java 1.5 also works, as documented.
Is the Kepler installer simply having problems finding the 64-bit Java binaries, or is 32-bit Java actually required? In either case, it would be helpful if the Kepler documentation provided more clarity on the matter, ideally with a note included on (or directly linked to) the downloads page. It is also confusing that the installer error complains about missing Java 1.5.0, but the user is prompted to install Java 6 (in conflict with the documentation).

Need to add a disclaimer to our download page that says that kepler is meant for 32 bit systems and that we have not tested it on 64 bit systems.
