Plugins pgpinline.dll, pgpmime.dll and pgpcore.dll do not provide version information in file properties window. But sizes (real size, not size on disk) and hashes for these files are as below:

Clawsmail is run from a batch file clawsmail.bat as follows:
 set HOMEDRIVE=
 set HOMEPATH=%~dp0..\clawsmail
 set USERPROFILE=%~dp0..\clawsmail

 start %~dp0..\clawsmail\claws-mail.exe
After loading plugin pgpinline.dll, claws-mail hangs. Claws-mail does not crash, meaning abnormal exit, but just stops responding. However, you can still close claws-mail from small X button on top right corner of it's window. Waiting for 3 minutes and it is still not responding, so draw conclusion that it will be so forever. However, from directory "Application Data" we can find that gnupg directory was created, among with files pubring.gpg, secring.gpg, trustdb.gpg (size 40 bytes, binary), S.gpg-agent (size 21 bytes, binary), pubring,kbx, pubring.gpg.lock, pubring.kbx.lock, secring.gpg.lock, trustdb.gpg.lock and one directory private-keys-v1.d. All filesizes 0 bytes if not otherwise stated.
