Since I installed windows 10 Adobe Photoshop 5.5 will not open. If I reinstall the program from my disc it will work for a while, than it will stop. Please help.

Photoshop 5.5 is pretty old. You'll probably need to run it with the Windows compatibility settings set to an older Windows version. And you'll need to use a scratch disk with less than 1 TB of space available (because the old Windows APIs couldn't handle larger disks).

Does your Photoshop 5.5 (1999 version, yes?) hang on startup? Like only the main window appears, but not the Photoshop logo, and then it stops responding?

I had that issue too with one of the two computers I've installed Windows 10 on: One was upgraded from Windows 7, the other was refreshed just hours ago.
On the upgraded machine, Photoshop 5.5 didn't work and when trying to reinstall, the installer would hang, too, but then on the refreshed computer, it installed and worked without any problems.

Back on the upgraded machine, I booted it in safe mode and the photoshop worked just fine. Back in regular mode, it hung again. I started disabling pointless services and startup items and then on next reboot, it worked.

Try your photoshop in safe mode. If it works there, you'll need to poke around your Windows install to see what's conflicting with your Photoshop loading. It otherwise DOES work.

I have tried so hard to get comfortable with later versions of Photoshop but 5.5's just perfect for me.

I agree I love 5.5. I was able to get Photoshop 5.5 working. It seems that disabling some programs working in the background was making it lag. It does take up a lot of memory when it runs. Thanks for the tips.

Photoshop 5.5 is so old that it can only use up to 2 Gig of your RAM (which isn't a lot on modern systems).

As near as I can tell, the Photoshop 5.0 installer is not compatible with Windows 10 x64. However, it is possible to run Photoshop 5.0 on Windows 10 64 bit.


Here's how I accomplished it, but proceed at your own risk. I recommend creating a restore point prior to continuing.


1. On a 32-bit Windows 10 computer, copy the "PHOTOSHP" folder and contents from the CD to the desktop (or other location.)

2. Run "setup.exe" in that folder as an administrator.

3. Complete the install of Photoshop 5.0 on your 32-bit pc.

4. Copy the following to a flash drive, or transfer using a network.

a. C:\Program Files\Adobe (all contents and sub-folders)

b. C:\Windows\KPCMS.INI

c. C:\Windows\System32 (any file that was modified the date of install)

5. On your 64-bit Windows 10 computer, copy the above files, into the same file structure. Do NOT overwrite any existing file.

6. Make sure you have a pagefile. No matter how much ram you have, Photoshop looks for a pagefile and calls it ram.

7. Reboot.

8. Locate and run "Photoshp.exe"


Note Photoshop will not show up as an installed program and will not show up on your Apps list. You will need to pin to start, add to your desktop, etc.

This explanation needs a little more detail for us folks who don't know about "pagefile" ... what that is... or where it is. 
I have had trouble with Photoshop 5.5 losing the ability to use any tools on certain jpgs.  After weeks of fucking around I found that "double clicking" a jpg would disable all tools.  I needed to "right click and select 'open' rather than double click.  Where is that corrupted bit of info saved?  With a Mac I can organize folders by "Date Modified" and that tool looks inside the folder.  Windows won't let me look in protected folders even after I reset permissions and log in as admin. so how do I organize by "Date Modified".
  I have resisted buying a new Windows 10 computer for fear I would lose Photoshop 5.5.  so it is nice to know (if you know how to do this) that I don't have to rule that out completely.

I solved the problem by installing on Linux under Wine.  Worked first time, no glitches at all.
