I am getting these errors. Severe: JRE 1.3 or higher must be installed! Severe: JDK 1.3 or higher must be installed!when installing JAI (Java Advanced Imaging) 1.1. Installing Zarafa Sme Server. 3 on Windows 7 (x64), with JRE 7 (1.7) installed at 'C: Program Files Java jre7' and JDK 7 (1.7) installed at 'C: Program Files Java jdk1.7.0'. Following, specifically this is what I did: Visited: • • (latest version) Downloaded: • • • • EDIT (QUESTION): It would be great if someone could break down the difference between these files.

The instructions at do not go into enough detail and assume you already know what's what. EDIT: As noted in the comments below, the. System Volume Information Size Vista. exe are exclusive installs, but I wished to install them to all three locations (to 'C: Program Files (x86) Sun Microsystems Java Advanced Imaging 1.1.3' as well as to my JDK and JRE locations), as I was not sure which I would need at my work as a Java developer. As far as I know, I just need to install the JDK version, and the.zip is a manual install of the same thing.
