LightRoom 5.6 Catalog error

Since installing LR V5.6 I keep getting the message:”Lightroom cannot use the catalog name “RHS Lightroom 5 Catalog” because it is not writable and cannot be opened. This could be caused by incorrect permissions or because another Lightroom application is using the catalog. You may try to correct the problem or you may select a different catalog.”
I have tried un/re-installing with no luck. Lightroom opens up OK for two or three times then up pops the message. Rebooting gets the same result. All OK for 2 or 3 loads then the error message appears.
Can anybody please advise.

The catalog file is located:

Data Storage D:\My Pictures\All Lightroom Catalogs\RHS Lightroom 5 Catalog

I have used the same location for years. I just rename the catalog when a new version of LR is issued. The problem did not exist before LR V5.6.

Thanks for your help.

Not clear here: You said Lightroom opens up two or three times then throws the message. How do you get it to work again? Or haven't you yet? Does rebooting allow you two or three more times?

Hi Rikk

Yes, if I reboot, LR opens up ok then pops up the message after opening 2 or 3 times.
Reboot again and the same happens.

Can I summarise my problems and further thoughts to help diagnose the problem..

Since installing LR V5.6 I keep getting the message:

”Lightroom cannot use the catalog name “RHS Lightroom 5 Catalog” because it is not writable and cannot be opened. This could be caused by incorrect permissions or because another Lightroom application is using the catalog. You may try to correct the problem or you may select a different catalog.”

I have tried un/re-installing with no luck.
Lightroom opens up OK for two or three times then up pops the message.

Rebooting gets the same result.
LR loads Ok on rebooting, all OK for 2 or 3 loads then the error message appears again.

I read somewhere that this message can appear when LR Produces a “.Lock” file to indicate that the database is in use elsewhere and that I should delete this file.
I tried this many times and LR produces the file again and continues to lock me out.
Therefore some program is using LR illegally.
At some stage I saw a very brief message to say that LR was being used by “CDP Controller.exe”
Can anybody help on this issue as my gut feeling is that this “CDP” program is locking me out?

What is a LOCK file?
Files that contain the .lock file extension are most commonly associated with Microsoft's .NET Framework. The LOCK file format is used to create "locked" copies of a database file.

When a database is already in use and another user tries to open it, a locked copy of the file will be opened instead of the editable copy. This file is saved with the .lock file suffix. This LOCK file prevents the user from making changes to the file while another user is editing it.

The Adobe Lightroom software application also uses the .lock file extension for locked database files.

This is as far as I have gone.

Can anybody please advise.

Hi all

Problem solved!

I noticed a very brief message to say "The file is open in CDP Controller.exe"
This meant that the file was locked by an external program.
I then remembered that I had recently installed "Dell Backup and Recovery".
One of the options in this program is "Data Backup" which contains the option "Continuous Data Protection".
What this does is to continually monitor all selected files and back them up accordingly.
One of the files I had asked Dell to monitor was my "Lightroom Catalog File".
Every time I changed any element of this file then Dell Data Backup would latch onto the file and back it up.
This program would then "Lock" the catalog but not "Unlock".
I changed the settings in the "Continuous Data Protection" to NOT monitor the LR Catalog file.

Hey Presto!

Problem solved!

I have given this solution in some detail to help any one else who experienced the same problem.

Thanks everybody for your help.
