I first installed the GPG4win-light-2.0 on my computer. When it is generating keys, the window “Enter passphrase” titled by “pinentry.exe” is popuped and it stoped, any characters couldn’t be inputed. It generated the keys without any passphrase inputed. I uninstalled it and tried to install GPG4win1.0.5. When runing, “The private key you selected as default is no longer available. GPA will try to choose a new default key automatically.” is printed, then “The GPGME library returned an unexpected error. The error was: General erro. This is probably a bug in GPA. GPA will now try to recover from this error.” was putted out.
My sistem is winXP.
