Here is the error code to the problem I posted about earlier. 

An error occurred while executing the action.

Technical details:

Unknown value for '^p' function: CSIDL_COMMON_DOCUMENTS

Unhandled exception during action ConcatEnvCreation

Failed to expand expression: "^e(ArgsDsyEnvMgt) -p "^e(PATH_DPCCustomCAA);^e(TARGET_PATH)" -from Env".

Action LaunchAppAction from feature CODE\\win_b64\\KnowledgeRuntimeViewInstaller failed.

Action ID: ConcatEnvCreation

What do I need to do to fix this?
