GPGOL breaks Enigmail

[Bob Henson]

I decided to try GPGOL for the few occasions that I use Outlook.
Unfortunately, since installing it, Enigmail's Key Management shows an empty
screen and I cannot use GnuPG via Enigmail at all. How do I get out of this,
please? In desperation I removed all the programs and registry entries that
I could find relating to GPGOL, but it hasn't helped.

Regards,

Bob
