How do I remove old profiles from my machine?

The best way to do this is to move unneeded profiles to a folder called "Disabled". In this way, if you accidentally delete a profile that you later need it can be fetched back.

Profiles are kept in the following places:

Windows XP and later C:\WINDOWS\SYSTEM32\SPOOL\DRIVERS\COLOR\
Windows 2000 C:\WINNT\SYSTEM32\SPOOL\DRIVERS\COLOR\
Windows NT C:\WINNT\SYSTEM32\COLOR\
Windows 98 C:\WINDOWS\SYSTEM\COLOR\
Windows 98SE C:\WINDOWS\SYSTEM\COLOR\
Windows ME C:\WINDOWS\SYSTEM\COLOR\

In detail:

  1. Open the relevant folder from the list above
  2. Create a folder called "Disabled" if you have not done so already
  3. It is probably best to see the list of profile names rather than the icons (View > Details)
  4. Drag unwanted profiles and drop them on Disabled.

Some profiles that I can see in Photoshop's Print with Preview Colour Management dialogue don't seem to be in the above COLOR folder. Where are they?

Profiles have an 'internal name' that is usually the same as the file name. Where this is not the case you need to make a guess at the likely file. Right-click on the file, choose Properties and Profile Information. This may give you enough information to decide if this is the profile you want.

If you copy unwanted profiles to the Disabled folder you can easily restore them again if you make a mistake.

In Photoshop Elements my images show 'Untagged RGB' instead of the 'sRGB' or 'Adobe RGB (1998)' as the colour space/profile. How do I set the colour space?

First, you should check your colour settings to ensure that full colour management is selected. Do this by:

  1. Edit > Color Settings ...
  2. Select 'Full Color Management' and click OK

In future, when an untagged image is first read in you should be presented with a dialogue relating to the colour space. Select 'Adobe RGB (1998)' and click OK.

If this does not happen, you can set the image to have Adobe RGB (1998) colour space by selecting (ticking) the Color/ICC Profile box in the 'Save As ...' dialogue when you next save the image.

Photoshop

I get the message 'Could not open "<filename>" because the file is not compatible with this version of Photoshop' when I try to open a Photoshop CS2 image in Photoshop 7. What is wrong?

There are two likely causes. The first, if you have Mac OS X, is that around November 2004 Norton Security corrupted some Photoshop files. It was expected that newer updates should have fixed this problem. See Adobe article.

The second is that there is a compatibility problem with the features you are using in Photoshop CS2. For example if you are using 16-bits per channel and have layers in your image.

I get the message 'Could not complete your request because the file is not compatible with this version of Photoshop' when I try to open a Photoshop CS2 image in Photoshop CS. What is wrong?

See the previous FAQ. Check whether converting to 8-bits per channel solves the problem. It is not clear why there should be a problem with 16-bit layers since both CS and CS2 support 16-bit layers.

When I save TIFF images the layers disappear. What is wrong?

It appears that Photoshop cannot save layers in 16-bit TIFF files.

When some TIFF files are opened in other applications parts of the image are white. What has happened?

If you have saved selections or created a channel yourself, perhaps as a mask (alpha channel) these will be copied to your saved file by default. To avoid your problems turn off "Save Alpha Channels" in the Save dialogue in Photoshop. It may also be worthwhile to flatten the image too to avoid any problems with applications that do not support layers.

I get some black thumbnails in Bridge. Can these be fixed?

Bridge keeps a temporary store of thumbnails (its cache) and this has got damaged slightly. All you need to do is go to Tools > Cache > Purge Cache for this Folder in Bridge. The next time you look at that folder in Bridge it will rebuild the necessary parts of the cache and you should now see your thumbnails. If you have flagged images with star ratings or labels, these will be lost.

I get black thumbnails for Photoshop (.PSD) files created in CS2. Can this be fixed.

It appears that thumbnail display for PSD files has been disabled in CS2. Thumbnails are still produced and so can be re-enabled. The link below provides the necessary files.

The instructions suggest you set a 'System Return Point' before changing the Registry - always a good idea. To do it on XP:

  1. Start > Help and Support
  2. Click on 'System Restore' (the surrounding words differ depending on your configuration, but you should see 'System Restore' somewhere on the page)
  3. Select 'Create a Restore Point' and click Next
  4. Give it a name such as 'Before CS2 thumbnail fix' and click Create
  5. Continue with the instructions from the above link.

WARNING: I have found that after installing this fix on one of my machines, one application quits suddenly when its Save As dialogue box opens. I am looking to see if similar problems occur in other applications.

How can I show thumbnails for RAW files in Windows Explorer (and in Photoshop dialogue boxes if you are viewing thumbnails there)?

Microsoft provide a 'power toy' to do this. Search for 'power toys raw microsoft' in Google. Click on 'RAW Image Thumbnailer and Viewer' and select Downloads. (The page layout and structure changes from time to time so you may have to look around.)

When you start the download, a small application 'Genuine Advantage' will be installed that checks that your Windows software is licenced and if so you can download the first part of the package. If you run the installer it will then download the rest of the package and install it.

During this process a dialog box is shown asking what RAW files you want it to open. UNCHECK all of them and click OK. You should now see thumbnails for your RAW images.
