Re: QTJ 6 Windows install

An addition to the following is that [2] should execute irrespectively if a
Java1.1 Sun JVM is found in the system (and irrespectively of [1] and [3] as I
had said). This is cause I just read in some e-mail a person complaining that
the client has to install the Sun JVM first! This shouldn't be needed if you
have the QTJ installer do what I say

I'd be glad to answer any questions you might have on it...
