GPG failing when run by application

If I run gpg to sign and encrypt a file from the command line, it works. I have an application that tries the same and I get the following error. The application has worked signing and encrypting before, so I do not think that it is a permission issue. Any ideas?

Running on windows. GnuPG 1.4.2.2

gpg: keyblock resource C:/Program Files/GNU/GnuPG" --output D:/WEA/ACH/milw472b.gpg --yes --batch --armor --recipient JPMC_ECS_PROD_2015 --default-key [email protected] --passphrase-fd 0 --no-verbose --sign --encrypt D:/WEA/ACH/ACH \secring.gpg': file open error gpg: keyblock resourceC:/Program Files/GNU/GnuPG" --output D:/WEA/ACH/milw472b.gpg --yes --batch --armor --recipient JPMC_ECS_PROD_2015 --default-key [email protected] --passphrase-fd 0 --no-verbose --sign --encrypt D:/WEA/ACH/ACH \pubring.gpg': file open error gpg: no valid OpenPGP data found. gpg: processing message failed: eof

Why is your program including the paths to the public and secret keyrings? GPG should find them in the home directory, if you're using a different location for those files then you either need to specify the new home directory (with the --homedir flag) or prepend the two keyring files with the relevant flags (--keyring and --secret-keyring).

As it is, that command appears to be trying to encrypt your public and secret keyrings to the "JPMC_ECS_PROD_2015" recipient. If "JPMC_ECS_PROD_2015" is not a group name (specified in the gpg.conf file) or specified elsewhere in the code for your program, then that will generate errors relating to an invalid recipient (or recipient format).
