Chasys Programs

I was browsing for free image editors which support layers when I stumbled upon John Paul Chacha's site.
The heading "Kenyan software at its very best" brought a smile to my face although I know that was very patronising of me.
Anyway, the program I looked at was Chasys Draw IES. It doesn't appear on the radar very often. I played with it for a while and was quite impressed. It had an appearance of quality about it.
Unfortunately I suspect that it is not portable - can an expert confirm that?

Also on the site there was a program Chasys Math (v 1.31)
This is a suite of math utilities including a calculator featuring graph-plotting, complex numbers and visually-perfect algebraic method (Chasys Math Calculator), and a matrix equation solver that can handle systems of equations as large as 32 by 32 (Chasys Math Matrix). It is probably portable. The files are obtained by installation/copy/uninstallation.

From a quick test (running the main executable artist.exe) i've done, Chasys Draw is not portable. Writes its settings to Common AppData. If you untick file associations, the only thing i saw in the registry is the association with its own format. Also i deleted the shell extension dll, as i always do before running the program

The second one is stealth, it doesn't write any settings

Chasys Draw is not portable, I posted a message on the developer's wish list board a long time ago requesting a portable version (and a few others did the same since then) but he never responded. Anyways, just re-tested V3.72.1 to confirm mrpink's findings:

user\public\Documents\Chasys Draw IES
settings.bin in user\all\Chasys Draw IES\Artist
settings.bin user\all\Chasys Draw IES\Version
user\all\Chasys Draw IES\Artist\autosave

HKEY_LOCAL_MACHINE\software\Classes\.cd5

Tested: Not Portable
