Request for list of files utilized in vb_api_register.bat and running pfclscom

Hello, I am currently working with my IT department to assess file privileges for using the VB_API in Creo 3.0.

Fortunately, we have managed to get everything working by writing a lot of broad rules.  Could someone tell me what files/dlls are involved in activating and using VB Api Register?  Here is what I have so far:

Access to Environment Variables:

user

PROE_INSTALL, is this necessary as a variable?

Admin access to system variables 

PRO_COMM_MSG_EXE, can this be a user instead of a system?

PFCLS_START_DIRECTORY,  is this necessary as a variable?

PRO_DIRECTORY,  is this necessary as a variable?

Admin Access to .bat files

vb_api_register.bat

vb_api_unregister.bat

Admin Access to .exe files

pro_comm_msg.exe

pfclscom.exe

parametric.exe

xtop.exe

creoagent.exe 'not sure about this one

Admin Access to .dll files

ucore46.dll

others?

Elevated privileges on excel.exe

Does anyone have a detailed list of admin files needed?  Any help would be appreciated.
