Attempting to download the 4.0.1 update from gives an error.

It's labeled as "Download 4.0.1 Update" in the description.

Yes when you can find time please, mrdav. Full install sets of international & hybrid iso's should always be accommodated.

by mrdav - 2014, September 29 - 8:35am

There used to be external links to a CD image with British, French and German installer and a hybrid iso image with British, French and German tutorial. Do you want them back? I have them.

I also think it's unnecessary.

Any need for having the recent uploaded "Photoshop_401.sit" (19.46 MB), 5th DL above?

It contains an installed copy of the Photoshop folder, missing all of the extensions and external files that get installed to the System Folder and has been pre-registered to some person.

We already have the full 4.01 install set in the 3rd DL above.

BUG NOTE! [...] "Been there, done that!"

I have struck this bug before, too. I think one work around for this that I tried with good results was by using a Disk Copy 6.x read/write disk image < 2GB, as the scratch disk volume. This I would also have auto-mount at start-up.

It's not an issue if using this program on Basilisk II or SheepShaver tho' because of their own drive container limits. Most software volumes for these emulators tend to be less than 2 GB

(I do not know why the smile face is there. Levity, I suppose!)

Its a Drupal bug (or feature) where an "s" followed by ")" will create a "drunken" smiley Drunk, this can be circumvented by using [square brackets] or by hard-coding the (parenthesis), if one can be bothered Wink

- It only seems to affect Comments made in the Apps & Games sections. Forum posts do not appear to have this issue

Photoshop four allows you two scratch disks. The PowerMac version allows volumes (not files, volumeDrunk larger than 2048MB. The Macintosh version will crash if a scratch file goes over 2048MB, which it can if the volume has enough free space. Using two scratch disks does not protect against this. “Been there, done that!

>guessing you might be after this.

Exactly so! The SDK is the only piece I want. Thanks for your work and excellent memory!

@Gary: The archived CD image file is 100% OK. Something is not going right at your end.

I downloaded it to test. It expands OK for me under Windows using unar.exe & also on beige G3, Mac OS 9.1, using Stuffit Expander 5.5

The expanded CD image "Adobe Photoshop®.toast" mounts fine in SheepShaver on Windows as a GUI added disk image and on the beige G3 using both Toast 5.2 and Virtual CD/DVD Utility (available here at the garden).

I MD5 checksummed the archive & the extracted image on both Windows & beige Mac, they matched:

7db104003d3416a943a7ad6d134fa2a8 *adobe_photoshopr.toast_.sit
c65e3a8960453a22421e93a8bcae127b *Adobe Photoshop®.toast

If you can check what you have, against those MD5 sums, it might help in determining their validity at your end.

[Edit] I've also added the SDK (4th DL above) taken from the toast image, guessing you might be after this.

by Gary - 2014, May 25 - 12:20pm

I've downloaded the toast.sit image twice now. Both times the download appears to work. Both times the SIT file expands. But when I try to mount the toast image, Toast reports that the image is in an unknown format.

I'm using Toast v5.2.3. Is my version wrong or is the archive file corrupted?


by shifuimam - 2013, March 9 - 7:56pm

I added a second download. The .hqx is a single read-only disk image containing the contents of all 21 installation floppies. I've tried it on my 68k IIci and the installer worked fine on the components I selected (not enough disk space to do a full install), so it SHOULD work.

Could someone please fix the Full CD iso image link? It links to a completely different site.
I've been looking for this.

Here are the photoshop 4.01 updates

by Centurion - 2012, October 2 - 10:39am

Umm, it seems the "Download full 4.0 CD (.iso, 435mb)" and "Download 4.0.1 Update" links are bad. skipping the ad redirects to a site about "The Internet vs Hollywood"

For sake of completeness, I uploaded the tutorial disk.
The disk should work with WIN31, 95 and NT as well as for the Classic MacOS.
For those using OSX, the videos should run with QT10.

Added the full application CD. There's also a tutorial disc but I don't have that.

by Pazaz - 2010, September 13 - 8:22pm

This was my favorite one, CS Came in 2003, I think CS1 was Adobe Photoshop 8.0 or something like that. CS5 must be like Adobe Photoshop 13/14

by turtlecroc - 2010, September 5 - 2:33am

Photoshop 4 is great. It was the biggest jump in functionality ever because it added layers. You can get by even today using PS4. Of course 5 added other things, e.g. realtime rotation and distortion, magnetic lasso, etc., but 4 was the quantum leap, and there's no reason on earth to use any version later than 5.5, even today. CS5..? make me puke.

Indeed I am. Photoshop 4 was the last major version to support 68k (given that it was released in 1996), and you can find proof of that by going to the "custom install" portion of the installer, where both 68k and PPC installs are listed.

68k? Are you sure?
