I encountered some problems with Scala (2.7) on Windows 7 64bit.
It seems that the paths used by Windows 7 for storing 32bit applications like Scala or Java
("C:\Program Files (x86)") break the batch scripts supplied in "/bin" with Scala 2.7.6/2.7.7RC1.
Runing any of them yields " "\Scala" kann syntaktisch an dieser Stelle nicht verarbeitet werden."
Installing Scala in a place not containing the "(x86)" in the paths leaves the same error for the Java path.
A workaround was setting the "_JAVACMD" variable to "java" in the supplied scripts.
