Looking back in the various postings in your discussion. I see and remeber that the criticle component that Adobe Creative Cloud Desktop App is.

But, one issue nit brought up.

Sometimes account issues may occur, now this is an account issue involving accreditation if the applications, and sometimes connectivity hick-ups. But this little bit should be probably tried anyhow

Bring up your copy of Adobe Creative Cloud Desktop App, I assume you are signed in. Sign out, then sign back in. Watch fir any notices appearing. This deactivates, then activates the applications. Do not do this without internet access.

David and All,

I believe that I may have found the solution to both problems.

In experimenting and checking settings; I discovered that: when launching the Adobe apps from the shortcuts in the Taskbar, I was not set to "Run as Administrator".  Upon changing that setting, when I now start the apps from the taskbar shortcut; each app starts without requesting that I log in again.

What I'm guessing had happened was, that when Adobe did the big major update, they set a flag somewhere in the installation module to set the user flag to not work as a not administrator (probably for security reasons).  While I have no other explaination for this and do not know how or why this works this way, at this point it seems to work.

Hope you helpful community people will find that helpful in your bag of tricks.

Hey All,

P.S

About backups

Backing the catalog up at exit only backups the catalog. The catalog is a database, it does not include the photos.

You need to backup photos separately

Do not place backups on the same drive as the files being backed up. That drive dies, both your work and the backups die. Hard drives die. Backup.

The program goes on the C drive. You do not need to worry exactly where each and every bit of code goes, the Adobe Creative Cloud Desktop App, that is used to install LrC, puts everything in the correct location (actually an ini file probably gets read, and followed)

Some of that can be found in the following somewhat dated link:

and

https://www.lightroomqueen.com/lightroom-classic-file-locations/

Moving on, the catalog can be placed wherever you want it, some points:

• It can be on any hard drive, internal or external
• It can benefit by being installed on to a faster hard drive
• The drive you place it on needs to have at least 20% free space, once the catalog is created, or edited.
• It should not be placed on network storage like a NAS (problematic)

The Camera RAW CACHE can be located wherever you want it, some points:

• Camera RAW CACHE can be located on any hard drive
• Do not locate ion a NAS
• It can benefit from a faster hard drive
• Normally the Camera RAW CACHE is purged at LrC closure (hmm, proof?)
• Try to avoid placing it on the same hard drive as your OS Paging file (competition for read/wrights)

Your photos can be on any hard drive. Some points:

•  Your Photos can be on a NAS
• Your photos can be on a network volume
• Using a faster hard drive has no benefit
• If using Smart Previews, the photos can be off line, untill you go to 1:1, and untill you export them. But this is not the norm.

If you cannot remember where your LrC catalog was, search the hard drives for .lrcat files

Although you can somewhat install all Adobe programs to some other drive than C the one porogram you can't install any other place is the CC Desktop App.

Also no matter where you install the other Adobe program some parts of them and other Adobe folder and files still get installed to the C drive.

If you somehow Moved those folder and file that is your problem.

I suggest you use the Cleaner tool to Remove Everything Adobe and als manually delete whatever folders and files you moved off the C drive (if you did that) then install the CC desktop app and then make the change in the CC app preferences to install the other program to whatever drive you want and then Leave Everything as it is by Default.

Second up, Adobe Creative Cloud Desktop App.

https://www.adobe.com/creativecloud/desktop-app.html

If you purchased a subscription plan, perhaps  the Photography Plan. Then you are no longer running the old stand alone applications.

The old stand alone applications used an install utility.

The subscription plan applications use the Adobe Creative Cloud Desktop App to accomplish the following (at least)

• Install the applications like PS, LR, LrC, Bridge, Camera RAW (for PS), and others
• Authenticate your rights to using the applications (i.e. subscription paid for)
• Activate the applications
• Update the applications
• Uninstall the applications (one way)
• Deactivate the applications
• Verify your subscription status (about every 90 days)

Now, you should be signing in via the Adobe Creative Cloud Desktop App. Normally, you do not want to sign out. If you sign out, then the applications get deactivated on that computer (and you would need to sign back in, or login ) So, do not sign out. (one reason to sign out is a diagnostic, if you are having accreditation issues, sign out, sign in, cross fingers)

Do not sign out if you are going to be without Internet, for example going on a trip. If you are signed in, and you loose the Internet, not a problem (unlessthat is for like 90 days)
