uninstall and reinstall calibre

[pippo53]

I have to uninstall and reinstall calibre but I don't want to redo all the calibre configurations (custom columns). How can I do?
Grazie

Uninstalling Calibre does not remove any configuration information - it just removes the binaries. I guess the question is what you are trying to achieve by uninstalling/reinstalling Calibre.

There are 2 family's of settings:
Per Library (like custom columns) that are part of the DB and what the prefs...Json file saves as a restore tool

And Per User, (AKA the configuration folder). Thes stor you plugins, overall settings that are not Per Library
Un-installing removes none of these.
You would need to destroy Metadata.db (which is the Library brains), to destroy custom columns. Not a good plan

Because after I deleted a partition from the Hard Disk the "app" folder results in "read only", which I can't change, and I can't use the "count page" app anymore

Thank you all

so :- create a new, empty app folder in a writeable location. Read from i.e. copy the read only folder contents and paste into that, then point calibre at the new app folder location ( somewhere in preferences). no need to uninstall nda re-install teh whole thing.

NB many other programs need access to the standard app folder locations in Windows , so if you have locked the whole area you will have other programs to repair.
try a "take ownership" freeware utility on app folder. once you "own it" you should be able to grant yourself write access.
e.g.

I use EC menu from here to give me a right click take ownership option

Count Pages is in the USERS config folder with all the rest of the installed PI, but it also makes use of your TEMP setting folder while running.
I would expect a lot more than Calibre PI to be giving you grief.

puzzled as to why deleting a partition should cause ownership/read only problems.
when I experience those , its because I have moved a drive ( with content) to a different PC, so windows thinks the original owner is AWOL - I changed what I use for the user account name a while back, so drives moved from old PCs have a "different" admin user/owner.
the freeware utilites will fix that
