Here's my fix for Forte installer hang on WinMe.
Hi all (all those with problems anyway :) ,
(I tried to post this in the Sun ONE Studio forum
but always got an error)
I had a problem installing Sun One Studio 4 Update 1.
It would keep freezing when it started searching for
the J2SDK, with the message: "Searching for suitable
J2SDK, please wait..".
Well, here's what worked for me on WinMe. Not all of
these steps may be necessary.
******************************************************
Install J2SDK to "C:\j2sdk1.4.1_01". First I uninstalled
it because it was in a folder with a space in the name. I
heard that was an issue with some OS's.
******************************************************
Create a text file containing the text "jh=C:\j2sdk1.4.1_01".
Close it and rename it as "ffj_ce_win32_en.sp". It's appar-
ently important that its name is the same as the installer,
except for the "sp" extension of course.
Put it into the same directory with ffj_ce_win32_en.exe
( the Forte installer ).
******************************************************
Leave the name of the Forte installer as original (instead
of renaming it to something more descriptive for example ).
Mine was named "ffj_ce_win32_en.exe".
******************************************************
In C:\Windows\
Rename java.exe to java-.exe
Rename javaw.exe to javaw-.exe
The important thing here is to make sure their new names are
unlikely to conflict with the names of any other files that
might be placed there later.
******************************************************
Now run the installer again and make it (finally !),
******************************************************
After I did all the above, it immediately found the correct
folder (instead of the usual freeze-up).
Hope this helps someone else too.
