I am running Calibre portable 2.64. I have several different ones - books to read, books read etc. I have just encountered an error in one of them when trying to add a book. This is the error

calibre, version 2.64.0
ERROR: Cannot add books: Failed to add any books, click "Show details" for more information.

Failed to start worker process
Traceback (most recent call last):

File "subprocess.py", line 958, in _execute_child
WindowsError: [Error 2] The system cannot find the file specified

At present there are 489 books in this library and at first I thought that maybe i had pinged the limit, however, my other libraries have more than that. I am not sure how to fix this. I can create another Calibre but I don't know how to copy the library over in the portable version.

Is anyone able to help? (apart from asking me to upgrade!)
