Amd display driver amdkmdap question

The System32 folder has atikmpag.sys 499kb dated 8/11/2016
The AMD (for Radeon R7 200) 16.12.1 downloaded yesterday with a clean install has atikmpag.sys 518 kb 12/7/2016

Since the 'clean' install was chosen from the Catalyst control panel and that routine did take place I wonder why the System 32/drivers has the 499Kb atikmpag.sys ?

I'm searching for why the graphic times out- and recovers when a routine is going on in Photoshop CC 2017 (Select and Mask a layer) The recovery had Photoshop have a blank screen and no response so end task in Taskmanager -many Adobe Cc dmp files (unreadable) Event viewer reports that a specific CC plug in (spaces libcef.dll) faulted as a result of amdkmdap stopped responding.
I was on Amd catalyst 16.11.4 (Nov2016) when the Photoshop CC was auto updated to CC 2017 and this freeze, restart issue occurred so I updated to the current 16.12.1 but there was no change. This edit using an edge mask still came to a halt and crash .
Using a 'fix' reported elsewhere of adding keyword value for time delay of 8 seconds produced the my first experience of a bsod...and subsequent repair/restore. Immediately removed that registry edit.

I cannot quite determine which is having an issue. Is it something in the display driver or is it that Photoshop introduced an issue with its accelerated gl?
After many 'pseudo crashes' Photoshop finally popped up a screen saying it had turned off acceleration so some tools would not be available.
Inquiries in the Adobe online forum results in a rep saying it is a problem of the graphics driver and update. (THAT did not prove to be a remedy)
So back to my original question....How come atikmpag in the System32/drivers is a smaller and older file? Is that the file Photoshop is referencing?

Re:I cannot quite determine which is having an issue.
Revisiting the photoshop forums it appears it is Photshop cc 2017 has the problem and so far the workaround is to rename the folder 'Regquired/Plugins/Spaces to be ~Spaces.-(calling that libcef.dll in that folder appears to be the conflict)

My immediate neighbour is 'America' but I (and we here in CA.) refer to it as the U.S. but we are influenced and effected by their structures including date format. My system uses Day, Month, Year .
As it turns out the issue has been with Adobe and as I type an update for Photoshop is in progress. The issue of not cooperating with the graphics driver has been widespread according to their forum and the feedback forum.
All these continuing upgrade/update downloads -seem to me- to be a breeding ground for errors. I don't see 'cumulative' being an asset.
