Installshield script

First off, Thanks for the essays...Ill admit it, im new at this, im not gonna try and be someone inm not. I really enjoyed the essays on Matlab, they were really helpfull, and saved me the few hundred i would have to dish out for the software i use at school every day.
I wrote a de-cryptor for the crypted intallshield.z files and found that it didn't quite work..(i had to write one in c since i don't have pascal)...upon closer inspection i noticed that the "key" wasn't in fact to xor with 1d,1a,1b,1c, but rather with 1d, 1c,1b,1a...perhaps this was changed in my version of Matlab?
Also, i couldn't decrypt the symbolic.z toolbox, it seems to have a different structure and the decrypter can't find the eof marker...(it goes well beyond 50 megs)..that could just be my code though. any insight into this?

and finally, once all of the files were dectypted, sure i can see them all, but matlab won't recognize them or show the icons to access their gui's... how can i get around this?

So for now, im trying a different approach, which is to tackle the installshield script instead. I have decompiled the .ins file and it seems quite interesting.....now i THINK i can modify it to allow the installation of all the toolboxes(i have been using a demo password which limits the install to simulink and matlab...with the dongle defeated and the license check removed..they work fine..thanks again)..

My main question is...if i recompile this sucker.....will it work, and what shuld i watch for in the scrip that would give access to the full(check components you wish to install) section.


Thanks Again, and i appologize for rambling.

Eco.
