[SOLVED] RapidMiner doesn't restart after finding rJava

crunch

Trying to get R perspective running. Have:

%R_HOME%       = \Programs\R\R-2.15.2
%JAVA_HOME% = \Programs\Java\jdk1.7.0_10
%Path%              = ... ;%R_HOME%\bin;%JAVA_HOME%\bin
(with core exes, namely R.exe & RScript.exe in %R_HOME%\bin with x64 exeutables in x64 subdir)

This worked before I repair installed Windows, but doesn't now:
%Path%              = ... ;%R_HOME%\bin\x64;%JAVA_HOME%\bin

After finding rJava and saying it will restart, it closes down, but never restarts.

Actually, somehow I stepped on the semicolon separating %R_HOME% from the rest of the path.  That causes it to get stuck.  The configuration it likes is with the Path containing %R_HOME%\bin\x64
