Can't open GPA?

I’ve changed nothing and it was working fine last night. This is the error code it gives me.

"The GPGME library returned an unexpected
error at confdialog.c:1472. The error was:

Invalid argument

This is either an installation problem or a bug in GPA.
GPA will now try to recover from this error."

I’ve tried uninstalling,repairing various windows clean ups.

I do have all of my keys so I’m not worried about that.[

This is also the 2nd error that pops up

"Fatal Error in GPGME library
(invoked from file options.c, line 302):

Unsupported protocol

The application will be terminated"

Hi R P,

from what you wrote, I guess that the problem is within the configuration.
(Which would explain why a reinstall does not help.)

Which version of Gpg4win are you using? (The current one?)

Does Kleopatra work? (Which is your alternative.)

Did you change any settings recently (around the time it was working)?
If you have a backup, you could compare the configuration files
from the backup with the current ones and see if there is a difference.
