wish is the command to launch Tcl/Tk, not ECLiPSe.

To launch TkECLiPSe, you should go to the program menu from what was the 
'Start' button of Windows, and select ECLiPSe 6.1 (64 bit)->TkECLiPSe. 
You can also create a short-cut for TkECLiPSe by dragging the TkECLiPSe 
menu item onto your desk-top.

I am guessing you are running 32 bit Java. Windows has this "feature" 
that when you run a 32 bit application (such as 32 bit Java), it 
silently maps everything to the 32 bit version -- paths, registry 
entries, etc. This allows you to write the same code and be able to run 
both 32 bit and 64 bit applications with it, but it makes it very hard 
to run a 64 bit application from within your 32 bit application. I think 
this is what is causing your problems.

To get around this, you should use 64 bit Java (assuming this is your 
problem).

[this actually might make it difficult to run an OutOfProcessEclipse of 
different word size from the Java Interface, not because you can't 
connect Java to an OutOfProcessEclipse of different word length, but 
because you can't easily launch an ECLiPSe of a different word length 
from within Java]

Cheers,

Kish
