Check the permissions on the folders that contain your images. Also check the permissions on the folder that contains your Lightroom catalog..
Jim thanks for your prompt response.
Yes I just went and checked the permissions on the new catalogs that are produced with LR 6.7. previous cat were vers 5
yes they both have the same read write access permissions.
Also checked the photo directories as well.
bear in mind system is set up for optimum performance with catelogs on one drive and images on another.
Checked permissions from top to bottom of the drives just to be sure.
ANother observation is that the error message as stated above when I execute lightroom, comes pretty well instantaneously. as If the program has not even opened or looked at any thing.
Still having file security issues with both photoshop and lightroom. I reinstalled both of them the other day, and theinstall process would only work if I was in admin mode.
now when I try to execute either lightroom or photoshop, they will only come up if I open them in admin mode.
both the directories of lightroom and photoshop have limited access defined in the acl's. plus all of the files in them have limited access in their security settings.
every thing only works if I open in admin mode.
I have installed previous versions of lightroom and photoshop on the same machine with no issues.
so I am after hints or solutions as to why this install has taken such a twist in stalling these products with limited windows file settings.
the security sessions of both are set up so that only admin can execute them.
Note running windows 10 on PC. Lightroom standalone 6.7 and photoshop cs6.
I'm not sure what to suggest. I seem to recall that right after I switched to Windows 10 I got that message. If I remember correctly, it was a permissions issue with the Pictures folder which is where the Lightroom catalog is created by default. Other than that, I have no idea what to suggest.
thanks jim - I am still picking up this prickly issue every morning to try to straighten it out. it looks like a local setting of some type - but have not cracked as of yet. my fall back is to run in admin mode.
