Richard,
Got to have some information first.

Yesterday, when you first opened the RAW images, whar color space (profile was applied?)
Do you have a special camera profile, or did you just let QU open the raws by default?
The default setting is saved in EDIT PREFERENCES, RAW OPTIONS.

See screen snap attached here.
You'll notice that mine has selected dots in Adobe and Enable custom Profiles (Located in the center)
What does yours say?

When you hover the mouse pointer over a raw thumbnail, what shows up in the HOTBAR, lower left corner of your screen?
See next snap
What you see there, does it have an  asterisk before and after the ICC Profile, or plain, like mine?
See last sample with asterisks.

Answer those, and we have a start

Did you do anything else with the images, like run them through some other application?
What is the camera?

Fred

OK Richard, you are not a Doofus.... a doofus would be afraid to ask his question in public. In truth, you have a good grasp of the profile stuff.

OK Here's the problem: Two symptoms coming from the same situarion.
Qimage Ultimate cannot find the file to rewrite when you make a change.
Qimage Ultimate cannot find the file it needs to fulfill the request to use the \pRGB.icm

Some how those problems are both coming from the fact that you installed Qimage placing these relevant files in the wrong location.

So, starting from the beginning, when you installed QU, did you BROWSE to a drive or folder that you thought would be a good place to store whatever Qimage was saving?
Even reinstalling wont fix that because I believe the installer remembers how you chose to do it last time, and tries to make you happy by putting the next version upgrade in the place you picked.

The correct location is \ProgramDATA\ddisoftware\Qimage...... and below that are all the subfolders that keep the stored files and profiles.

I would click on UTILITIES in Qimage and use the MIGRATE selection and let Q move the files to the right location.
If you are confortable moving files, you can do that manually.

Also use Utilities, and Explore Application data.... see 050 screen snap.  You can see it all there.    See that Raw cache folder? That's where QU has to write the changes you make.

I think you have enough to fix it, and if not, I'm here most of the time. If not, someone else will fix you up.

Fred et al

To begin with, when I installed the trial version of Q-U, I did not specify a location different from what the installation had chosen.  The only thing I have done recently is to delete a bunch of junk from my system including uninstalling miscellaneous software I was perusing. At no time did I consciously delete files from the Qimage folder that were in the ddisoftware folder....of course I may for a moment or two been unconscious...but whose counting.
More strangeness:  I found the INSTALL txt file under Q-U and it disclosed that the following items should be in the Qimage folder; namely,
                     
\ddisoftware\Qimage\pRGB.icm
\ddisoftware\Qimage\Adobe.icm
\ddisoftware\Qimage\Apple.icm
\ddisoftware\Qimage\bruce.icm
\ddisoftware\Qimage\cie.icm
\ddisoftware\Qimage\Cmatch.icm
\ddisoftware\Qimage\errbmp.bmp
\ddisoftware\Qimage\q.bmp
\ddisoftware\Qimage\ntsc.icm
\ddisoftware\Qimage\pc-mntr.icm
\ddisoftware\Qimage\sRGB.icm
\ddisoftware\Qimage\wide.icm 

Ready for this?  NOT A SINGLE ONE OF THEM WERE THERE!!  Further, I did a search of my system for them and it came back NADA........

Per Fred's suggestion I tried the Migrate routine and nothing...not surprising if you factor in the fact they are not in the system.  Nonetheless, I am purchasing Q-U today and will first, of course, uninstall the trial version. I will also probably run a reg cleaner.  Anyone with additional suggestions so my download will be free of any artifacts? Thanks again.

Richard

ooooh!
He's listening.
You better make your purchase quickly before he sabotages your download.
