Your image shows two messages:

There is a message

> `ERROR:root:Couldn't open wallet.dat/main`

It suggests you should close Bitcoin if it is already running. I would use Windows' task-manager to see if bitcoin-qt, bitcoind etc are running (`Ctrl`+`Alt`+`Del` in Windows-10 should bring up a menu from which you can select `task-manager`). You can close those processes from task manager if necessary.

Since your screenshot shows a second attempt without this error, it looks like you shut down Botcoin-qt OK and the command completed OK.

and

> `WARNING:root:pycrypto or libssl not found, decryption may be slow`

This is just a warning, it doesn't mean that the command won't work, just that it may take longer than normal.

The message suggests pywallet will use slow internal cryptographic functions if it doesn't have access to a fast external library of cryptographic functions.

So your `wallet.txt` file should show you the information you wanted to extract.
