I just installed EasyTex on a Win95 computer and it ran ok.
I used the installer downloaded from here:
http://uaf.sourceforge.net/phalzyr/EasyWallTexz.exe
and after I installed it and ran it for the first time I saw the default wall in 640x480 format. Mostly a black screen except for the small wall layout in the bottom left corner.
My folder for easytex has this in it:
EasyTex:
EasyWallTex.exe
ijl15.dll
libpng.dll
readme.txt
EasyTex->Data:
bounds.txt
ceiling.bmp
config.txt
events.txt
floor.bmp
wall1.bmp
wall2.bmp
world.txt
Does this match yours?
