Hi Roger:

Would be curious to hear what happened with your uninstall. I encountered a similar situation, checked with NAPP due to the many problems I have had with Adobe Support. The uninstall almost worked.

However, when I removed CS4 from my lap top, the CS5 executable programs disappeared from <Start> <All Programs> <Adobe>. I used Explorer to see what files were installed, and they were all there. So I either have to execute them from Explorer, or reinstall to make life a bit easier. So I am in the process of reinstalling. Think I will leave both sets on my Desktop.

Below is the information NAPP sent me. There are some good hints if you have customized Actions.

From NAPP:

  You can uninstall through Start menu> Control Panel> Add and Remove Programs.   But before you do, consider these steps:

--Open Photoshop CS4.

--In the Actions palette, select a set of custom Actions (a set, not an individual Action).

--From the Actions palette menu select Save Actions.

--Choose a location, assign a name (using the .atn file extension), click Save.

--Repeat for any additional sets of Actions.

--If you have any custom brushes, styles, etc., use Edit> Preset Manager to create and save sets.

--Quit Photoshop CS4.

--Open Photoshop CS5.

--From the Actions palette menu choose Load Actions.

--Navigate to and select your .atn files to load them into the palette.

--Use Edit> Preset Manager to load other custom items.

  Also check the other programs of the Creative Suite for custom templates and such that you want to save.

Someone from Adobe should have responded, but I saw in their readme that uninstalling CS4 after installing CS5 removes CS5 files!!! They should have warned users more prominently when installing CS5. It would be wise to uninstall CS5 first and then CS4. Dumb, but necessary.

I just uninstalled CS4 Design Premium after installing CS5 Design Premium. Everything appears to be working just fine. I was actually using Photoshop CS5 during most of the uninstall process. As with any install or uninstall I would recommend backing anything up that is important to you. That said, you should be able to safely uninstall CS4 after installing CS5.

I would also recommend deactivating your CS4 prior to uninstall just to be safe. I'll post on this thread if I end up running into any problems down the line.

I am not sure if that will fix the problem, but you should try it out.

If you like to invest the time & effort, you can uninstall everything and re-install only CS5. Back-up your files first.

Chris, thanks for your response, particularly the reminder to deactivate the account.  I wouldn't have thought about that.

Take care,

Debbie

I had the same issue as some of you -I left CS4 on my system in case there was a problem with CS5, and then afterwards assumed that using the CS4 uninstaller would _only_ uninstall CS4 files. This help page seems to answer to that problem: http://kb2.adobe.com/cps/407/kb407726.html -And indeed it worked for me. I had to grab the missing file "Adobe Unit Types.osax" from my backup -A file named "Adobe Unit Types" had been left in the current Library but "Adobe Unit Types.osax" was not there -that was presumably removed by the CS4 uninstaller. {The correct location is your machine's [root=hard drive]/Library, rather than [user]/Library or [root]/System/Library.} Authenticate to restore the file, and Photoshop should launch properly.

Re: the other thread, my activation/deactivation story was also unpredictable and not what the Adobe rep expected, but it managed to resolve automatically in my favor. Seems glitchy to me-Good luck!
