Add files to selected book records

[Dan__]

Hello,
I haven't done this for the past few versions but tried today with 6.3 and then with 6.2.1 and got the following. Any suggestions.

Thank you

calibre, version 6.2.1
ERROR: Unhandled exception: <b>Exception</b>:File dialog failed (return code 3221225477):

Version 6.3 on Windows 10 works for me. I just used the all three methods successfully:

1. Drag and Drop into Book details panel;
2. Add Books->Add files to selected book records from clipboard (that I copied using Ctrl+C in explorer)
3. Add Books->Add files to selected book records (that uses the standard file open)

Third party file managers that replace Windows File Explorer have been known to cause these sort of issues.

Something on your computer, most likely the anti-virus, is blocking the calibre
helper process for file dialogs (calibre-file-dialog.exe). Disable the
antivirus or add an exception for calibre-file-dialog.exe and you should be
fine. Alternatively, you can tell calibre to not use native file dialogs, which
avoids the helper process, by setting the CALIBRE_NO_NATIVE_FILEDIALOGS
environment variable to 1 as described here:
