Did you get these presets from a Mac user?
According to this article, ds_store files can safely be deleted.
You could make a copy of a folder and delete the file, and see if it causes any problems.
I purchased them from Online advertised sources. As I stated above, even after deleting these files I STILL get the error.
Sorry, I didn't read your post carefully enough.
I have had similar issues myself when copying folders, can't remember the details, but I think a computer restart helped.
Restarting the computer does not help
Your .lrtemplate file is apparently owned by another user or group on the computer. Normally you'd get a plain-text version of the username, but apparently your current user can't even determine that so it is showing the internal user-GUID, instead.
Right-click on the file or maybe the folder the templates are in, choose Properties, then Security, and click through the tabs and options to see how the owner of the file is. If you are truly an Administrator on the computer and that Administrator has rights to the folder the files are in then you should be able to change ownership to yourself or at least the Administrators group you're hopefully a member of.
I truly am 'the' Administrator on the computer. I am included in the Administrator Group. I also added myself directly to the permissions of the folder with FULL Control.
I can't copy the Presets to Lightroom.
When I try I first get a message saying I need Administrator permissions to do so with the option to click OK. I click OK and then am prompted with the message listed in the attached image at the beginning of this thread.
I've successfully copied all but 2 preset folders to lightroom. Just can't get the last 2.
What user is it that you require permission from, the one with a SID of S-1-5-21-288...? What user owns the file? What users owns the folder you're copying into or the file you're copying over the top of if that's the current situation? Is your virus scanner interfering? Do a ScanDisk/CHKDSK to make sure the security information isn't corrupted. What is the folder path you're copying these template files to? Is it one that could be controlled by the OS as a protected folder?
How would I know or check what user owns that file? As mentioned prior, I am the Administrator of this machine. I am the only user of the machine. The folders I am copying to is the Lighroom Delevop Preset folder. Administrator has Full Control of this folder. The folder I am copying from is the Download folder. Administrator as Full Control of this folder as well. Not sure how my Microsoft Security Essentials could possibly be interfering with copying the file however, I will try again with it disabled.
