Thank you.  That makes perfect sense given the symptoms reported.

It does leave people who can't get updates to existing driver software kind of out in the cold, though.

You *could* tie the behavior to whether Photoshop is being run in a compatibility mode...  Just a thought.

Further to my earlier post re. " "This application has failed to start because PMDDTW5.dll was not found. Re-installing the application may fix the problem.":

     After I reinstalled the scanner drivers, I also then had to copy the missing .dll from the C:\Windows\'Twain....' folder into the C:\Program Files\Adobe\Adobe Photoshop folder. As soon as I did that everything returned to normal. Obviously the updater had removed that .dll  during the Adobe update. If you haven't physically moved your missing .dll into the correct Adobe folder, chances are you won't have solved the problem even by reinstalling the scanner software. Just a reinstall of the scanner drivers is not enough. Hope that helps someone.....................................frank

In layman's terms, Photoshop accesses the driver, and the driver loads its DLLs.

Some drivers don't load their DLLs using an explicit path, which is now required because Adobe has changed the run-time policy in Photoshop to require it, per modern Windows standards.

Ergo, some scanner drivers that used to load DLLs successfully now no longer do so, because of the policy change in Photoshop.

JUST GUESSING HERE:  Apparently there have been security breaches because of the older, more liberal policy, and Adobe may have suffered some liability.

The good news is there may be a workaround (based on playz123's post above):  Find and copy the scanner driver DLL that is failing to load into the Photoshop program folder.

Hello from France (and sorry for my bad english...). I was looking for a solution to the problem of the (now) famous dll "dragnkl.dll" because I have a Nikon CoolScan V ED and, of course, since the last update of PS CS5, the scanner didn't want to work from PS anymore. I noticed the answer from Noel Carboni : try to copy and paste the missing dll in the PS folder. In fact, I copied all the dll from Nikon to PS and now, it's done : I can use the Nikon Scan directly from PS again. So, thank you for all !

It does not work for me.

I copied all dll files from Windows>Twain_32>Nikon>NikonScan to the CS5 plugin>import-export folder, but I get the error message again.

Am I doing something wrong?

Matthew.

I got it! And it works! Thank you very much! 

Of course I understand this is only a workaround untill there is a final solution.

Thanks again!

Matthew.

As I said in my original post, which Noel then referenced, I did NOT have to put all the scanner files in the Photoshop folder, only the one that was reported missing when I was booting Photoshop. I suspect if someone puts all the scanner files in that folder, someone may still have problems. Just replace what Photoshop reports is missing, and see if that solves it. As I also reported, that's what worked for me (but I can't guarantee it will work for everyone).................frank

Hello, as darkon-pl said, the second way works fine for me, I edited the path variable from W7 system, and I deleted all the dll previously added in PS folder. All is right, the Nikon scan works with PS.

So, it's useless to copy the files AND to edit the path variable, just edit path.

Hi darcom-pl

Your second solution - edit the environmental variable PATH, works perfectly.

Thank you for an effective and elegant solution.

Just to clarify.......  After editing environmental variable path scanner now works fine from within CS5 but tool  tips are still missing; i.e., tool tips dialogue boxes come up blank.

Your post helped me. It worked also for my Epson scanner. I extended the path variable with the location of the twain drivers "%windir%\twain_32\{driver_specific_directory}"

Thanks

ok, I found third solution.
I made a launcher for photoshop.
You can download it from here:
http://rapidshare.com/files/437066686/ps.exe
This is basicly batch file compiled to exe, which contains:
  path=%windir%\twain_32\Nikon\Nikon Scan 4.0;
  start Photoshop.exe

With this solution you don't need to change any system settings or copy dlls

I just checked for updates and found 12.0.3 update is now available. The narrative claims it fixes the Tool Tip problem under XP and...

When I click the "Information" link, it takes me to the 12.0.2, not 12.0.3, update information - nothing new there.

Does the 12.0.3 update fix the TWAIN problem under Windows? Does it break the work around of editing the PATH environmental variable that works now?

After being "bitten" by the 12.0.2 update, I am reluctant to install Photoshop updates until I have heard from other, more "adventurous" souls <grin>

Anyone using NikonScan tried this update yet?

Has Adobe tested using NikonScan this time around?

I confirm that the problem has been fixed by the last update.

NikonScan now works without problems.

Thank you, Adobe.

Happy Holidays.
