Windows 7: Something stops PyQt from installing?!

06 Nov 2014   #1

Something stops PyQt from installing?!

I don't know if anyone has any ideas. I have been using the app calibre for years. It uses PyQt. I have been using the Edit Book feature ever since it was implemented.
Now it returns the error PyQt5.Core not found. It isn't there.
Any ideas as to what could cause this?

There is no point in checking what I have installed since the last time the edit function worked, there are at least 30 apps which have updated since then.

Do you have the latest SIP installed? Are you trying to download/install PyQT5 from the official Riverbank software site? You might want to contact Riverbank Computing directly for additional help: info<at>riverbankcomputing<dot>com

Actually, no, I am installing calibre. It is a book database.
But contacting Riverbank is not a bad idea.
