@ Piru - Whatever happens, I really do appreciate you taking an interest in this issue, and I personally won't be sending a bug report to the MorphOS Development Team (Bug HQ) - even if it might have warranted it, regarding this SVG icon issue, or whatever it turns out to be, as I know you will do whatever you can to try to look into the issue(s) causing the ImageFX v4.5 installation to fail for emeck.

I got the impression that emeck had only used 68k installers, and had not swapped any of those installers for the MorphOS executable Installer in preference for any of the 68k executable installers, though I feel sure you'd want to get that information directly from emeck himself.

The ImageFX v4.5 CD Installer is the v43.3 68k Installer (from 30-04-1996)

Line 1657 to 1671 are set out below from my copy of ImageFX v4.5

1657 ;-------------------
1658 ; Create destination directory if it doesn't already exist.
1659 ;(onerror
1660 ; (abort "Cannot create directory `%ls'. (There may be a file "
1661 ; "already there with the same name.)" wheredir)
1662 ;)
1663 (makedir wheredir (infos))
1664
1665 ;-------------------
1666 ; Save all the user's old stuff
1667
1668 ;(makedir (tackon wheredir "Storage"))
1669 ;(makedir (tackon wheredir "Storage/Convolve"))
1670 ;(makedir (tackon wheredir "Storage/Transform"))
1671 ;(makedir (tackon wheredir "Storage/Palettes"))

If you need more of the install script then I can supply that . . . or you can wait for emeck to reply if you prefer.

On the ImageFX v4.5 CD there is also a MorphOS installation script named "Install_MOS" (300 lines long) that is there to install the PowerStation Volume 1 PPC module add-ons only for MorphOS.

At the bottom of that script is a comment ...
"; 22.09.03 djc Changed to support ImageFX4 under MorphOS-includes PNGIcons."

So, probably support for PNG Icons had only just been implemented into ImageFX v4.x?

When I run the "Install_MOS" script with the MorphOS Installer by Guido Mersmann, then I get to about line 130 where the installation comes across a "fatal error" and quits. I believe this too is related to directory creation within MorphOS, as this section from Line 130 to 135 states:

130 (copyfiles
131 (source "PPC/PowerStation_MorphOS/storage/")
132 (dest (tackon wheredir "Modules/PowerUp"))
133 (pattern "#?.elf")
134 (optional "oknodelete" "force" "askuser")
135 )

If I then create manually the directory PowerUp in the Modules directory then when I run the Installer program and the same Install_MOS script then it continues past this point and fully completes its task.

Hope this is of some use to understanding the problem, and working out if anything else can be done to fix the ImageFX Install script(s).
