Multiple Unhandled Exceptions

[Spittie]

Greetings,
New member here, but I've been using mobile readers and Calibre for quite some time. Admittedly, I'm a bit sporadic with Calibre, but I recently downloaded the update and had a few errors that I could use help with if you would be so kind.

If I hit 'Find Duplicates' I get an ERROR:Unhandled Exception. When I attempt 'Library Maintenance' I also get an Unhandled Exception. There may be more functions that would result in errors, but I haven't dived in too deeply.

Some details are below.

Thanks in advance.

Paul

I'm running Windows 8.1 and downloaded and installed 'calbre-64bit-5.6.0.msi'.

Here is the 'Find Duplicate' error log:

First thing to do is to upgrade to Windows 10. Then try again.

Why Jon? Please quit making this your first suggestion.

First thing I'd do is make sure all plugins are up-to-date.

Maybe the fact that find duplicates is at version 1.8.0 and the log shows 1.6.3.....

That is a good idea. The Find Duplicates plugin is not the current version.

Brilliant!
I updated all installed plugins and both errors are gone.
As I said, I am a bit of a Calibre newb even though I've 'used' it for some time.

Nonetheless, thank you gentlemen!

I look forward to exploring the forum and getting a bit better acquainted.

Best,
Paul

Whenever Calibre notifies you of a plugin update, click the link and go get the new version(s).
