Appsense Error Code=32

Im using Appsense v7.227 Environment Manager to deliver a hybrid profile to Terminal server users. I hive off a small number of required registry keys on logoff and import them back in on logon. I perform a redirect on users file areas (appdata,desktop,favorites,cookies)

On running a trace for the logon process with the appsense tool EM_DebugGUI_v7.0.exe
I saw a number of error messages. A few were error code=32 (full message at the bottom)
The reg import does however appear to be succesful so i think the message may just be a red herring.

The error only seems to appear for registry keys that i was importing in the MERGE mode. All REPLACE mode keys were ok. Changing the option to REPLACE did not show the problem. I have a call open with Appsense into why MERGE mode produces the error code.

[CRegistryHiveObject::CopyAndBackup71Hive] ERROR: Failed to update hive filename from "hybridpath" to "hybridpath" , error code=32

I raised a call with Appsense Support for this, they have basically said this is an acceptable error message in this event.

I have performed more debug traces and i now see error code 32's with REPLACE mode registry keys, As before the registry does however seem to have imported the hive succesfully.
So again im going to have to ignore these errors.
