Python Conflicts

[iwefsod]

Hi everybody,

Since upgrading to Calibre 5, I've lost some functionality due to Python conflicts. The two main issues I've had are when trying to download metadata or reach the plugin index page. I'm using the portable version of Calibre 5.3. Here are the two error messages respectively:

Download metadata:

Thanks very much!

That looks like you have a messed up install. python27.dll is no longer part of calibre. Try deleting all the file inside the calibre folder inside the calibre portable folder then re-install.

That did the trick! Thanks so much for the quick answer, and thank you always for the wonderful software, Kovid.
