After changing computers Lightroom classic can't open catalog "file not writable"

[remolder]

I got a new computer and copied all my photos and catalog etc. to the new computer. When I try to open the catalog I get the error that says it can't open the because the file is not writable. I changed all the permissions on the catalog, photos so that they are read/write by everyone. I am on windows 10 home and the only user so I am an administrator. Have I lost all my work?

What happens if you put the catalog file into a newly created folder as under Pictures?

This resolved my problem after moving the catalog file from external drive to Pictures on the PC and opening the file there. Thank you dj_paige!

Also, using Windows File Explorer, check the ownership of the catalog file. Since it came from a different computer, while your username may match on the new computer, your ID may not.

If that is the case, you should be able to either "take ownership" of the file or give "everyone" read and write privs to the file.

How do you "give "everyone" read and write privs" to an entire external drive ?

I have the same problem working on an external drive I share between 2 computers.

Now my Lightroom catalog cannot be opened anymore on both computers. Note that I cleaned the drive with windows utilities before because the .lock file remained and could not be deleted. I also had the problem not being able to save back up versions in the past when closing my lightroom project.

I don't understand why this shoud be a permission problem, because on the same drive, I currently work on premiere pro and after effects projects which have no problem recording the project file.

Plus I succedeed to open another LR project on the same drive. It just looks like the project is corrupted, nothing to do with windows permissions.

Help !

Dear Adobe,

it looks like my catalog is corrupt and I cannot find any other support choice for LR than forums in the creative cloud interface.

Where can I send you my catalog for analysis ?

Help needed urgently, I cannot access my work anymore.
