Install 6.18 error

I have a persistent error when running version 6.18

I have uninstalled everything. I have deleted all folders that say calibre including the programs folder.

I have deleted all tmp files. But still calibre starts with an error saying that the database folder has a bad location and to choose another. No mater what location I choose, the same thing happens and calibre aborts.

The specific error message I get is:

Traceback (most recent call last):
File "site-packages\calibre\gui2\main.py", line 424, in __init__
File "site-packages\calibre\library\database2.py", line 417, in __init__

File "site-packages\calibre\library\database2.py", line 456, in initialize_database

Sound like something that happened to me a few times. You get this msg and then it exits? start calibre again. this time when it ask you to choose a folder for your library, browse to your old Library folder. It should accept this and you are in business.

Well, you had to name it something to start with didn't you? The library is where Calibre stores the ebook files. Unless you created this folder in the same location under program files as Calibre was installed to, you most likely didn't delete it. You could do a search for it using a known subfolder like library or calibre or I think there is one called books you could try those to find out what the main library folder was called.

I assume you are choosing an existing folder in a location that the user you are logged in as has full permissions to?

Your best bet is to create a folder named calibre in your Home folder (The one that you get to when you click on your username on the left side of finder) or your Documents folder.

Once that folder is created run calibre and point to the folder that you just made.

hmmmm.. Corrrection. those folders are on my sdcard for my reader. The structure of the library file is simpler. Each folder is the name of a book author. So just do a search for a folder with the name of an author you had in your old library.

Did you delete ~/Library/Preferences/net.kovidgoyle.calibre.plist and ~/Library/Preferences/calibre

??

I did not delete ~/Library/Preferences/net.kovidgoyle.calibre.plist

I am using XP Pro

Can I just name a new folder or does it have to be the "old" folder.

I deleted everything so I thought it would be a fresh install. I guess I am wrong.

Can I do a search for the bad database? What should I search for?

Well this may be a case of the blind leading the blind here. Bob clearly has a lot more experience with Calibre than I do, but I think he is using a different OS than we are. I also have WinXP pro and when I first installed Calibre I created a folder for my library called Epub. Calibre transferred each file I added to this in a subfolder with the author's name. If there were more than one book by the same author, it got its own subfolder. Thats why you have to be careful to always spell the author the same way. Anyway that why I said do a search in windows for the folder named for an author you know you had in the old library. That will lead you to the name of your initial library folder.
Oh I should add that the root library folder(whatever you named it has the file metadata.db This is the database file Calibre looks for. To be honest with you I don't know how you would get Calibre to recreate this file if you have to create a new library folder. It seems to be a SQLite db file

I deleted from my computer all metadata.db files, but same problem. I just want to install it fresh.

I had to revert my computer and I have no idea where the database is.

If you are using XP Pro, have you deleted the folder
C:\Documents and Settings\your_user_name\Application Data\Calibre
This is where any setting from previous installs are stored. If you delete that you should be prompted for a folder to be used for the new Calibre library you are about to create.
