"C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\PSViews.dll" 9/16/2012 7:15PM (2,358,360 bytes)
"C:\Program Files (x86)\Adobe\Adobe Photoshop CS6\PSViews.dll" 9/16/2012 5:50pm (2,358,360 bytes)
OS is XP nas PS CS6
the file I have found is:
"C:\Program Files\Adobe\Adobe Photoshop CS6\PSViews.dll" (327,680 bytes)
Ther seems to be a big difference in fils size between what you found an what I find?????
I have noticed that.
what can be the reason?
can it be replaced?
Check your backup if you have one otherwise re-install Photoshop on top of itssef.
