Thank you for the response.  The videos, ironically, were all from the Luminous Landscape on how to use LR and Photoshop.  They were in a separate folder on my data drive and have never been cached by LR until I updated to ver 8.2.1 the other week.  I don't shoot video at all.  I guess I should not be surprised about the bug in LR and Adobe not wanting to waste time fixing it.  I had to update from Win 8.1 to Win 10 because LR is no longer supported on the previous version of Windows and my Nikon Z6 was useless in terms of LR unless I updated.  Thank you for telling me where the Purge Cache setting is.  I've eliminated all the movie files. ...

Thanks, I guess I need to call Adobe support and ask for a refund since I'm running 8.1 and the product won't work. ... View more

This is a major bummer.  I just got a new Nikon Z 6 last week and moved up from my perpetual license LR to LR CC.  I'm running Windows 8.1 and just figured that the software would be backward compatible like virtually everything else.  LR installed but only Version 7.5 and Camera Raw 10.1.  This does me no good at all!!!!!  Does anyone know whether Adobe has plans to fix this?  I don't want to do a Win 10 install on my workstation because of all the programs that currently work just fine! ...

Andrew, Argyll can print out in user defined resolution. All my targets are 100ppi and I've confirmed this in Photoshop. I'm not sure rescaling will help on this. Alan ... View more

Thanks for the suggestion, I will post this at that site as well. The problem with the ACPU is that it reduces the ArgyllCMS patch sets by just under 3%. I don't have any problems with patch sets printed out using ACPU for an i1 Pro since the shrinkage is negligible for purposes of this spectro and I get good reads and resulting profiles. The user with the DTP20 cannot read a row of patches without encountering an error. The thread describing the issue is here: http://www.freelists.org/post/argyllcms/DTP20-Pulse-patch-size-error It may be that the patch size tolerance is so tight that a 3% shrinkage results in unreadable patches. I've printed out patch sets using PS CS5 and you can see the size difference visually. Of course you cannot use CS5 to print out patches for profiling because of the color management issue (I do have CS4 but have not compared readings between patch sets printed out there vs the ACPU; it may be that there is no difference at all). I hope this explains things a little better. ... View more

There are still users of this utility that are having problems because the utility does not print targets with absolute fidelity.  Under Win7, 64 bit, I have some ArgyllCMS targets designed for an i1 Pro and the targets are reduced in size by 2.7%.  It appears to me that the utility attempts to center the target whether or not it is centered on the original page.  If I print the target from Photoshop it is the original size but I can only print targets using CS4 because CS5 won't print without color management.  This bug did not affect the ability of the i1 Pro to read the patches but another Argyll user cannot print a patch set DTP20 that is readable.  Does Adobe plan to address this bug in an update? ...
