Working on a migration to SI 5.2 project, I installed a new version of Map Editor (8.***). But when I tried to test my map, I got an error: “A Java 1.7 Runtime Environment must be installed to use this function, but one could not be located. Please install a Java 1.7 Runtime Environment and retry this operation.”. I downloaded Java 1.7 JRE from here, installed it – but it didn’t help :-|. “java -version” gives me “1.7” but Map Editor didn’t “see” it. I checked the registry keys it looked for and found that it tried to use HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\1.7 , but I didn’t have one. So, as a temporary solution I added it to the registry (just copied it from existing 1.6) – and now it works fine. Not sure about my “solution” here, but it works for me and I have no time to find out what was the exact reason of my problems.
