VPN error: 3DES not a choice for encryption

When you are working with an IKE policy transform, data policy transform, or a manual connection, the 3DES encryption algorithm is not a choice.

Symptom:
When working with an IKE policy transform, data policy transform, or a manual connection, the 3DES encryption algorithm is not a choice.
Possible resolution:
Most likely, you only have the Cryptographic Access Provider AC2 (5722-AC2) product installed on your system, and not Cryptographic Access Provider AC3 (5722-AC3). AC2 only allows for the Data Encryption Standard (DES) encryption algorithm due to restrictions on key lengths.
