If you have installed and activated the VMEP CRM integration component, but get this error when clicking the Service Manager Administration icon under CRM Administration (you have to disable friendly http error messages):

Active Server Pages error 'ASP 0131'

Disallowed Parent Path

/crm/CustomPages/Technisoft/Config/Config_Base.asp, line 1

The Include file '../../Sage300crmdpp.js' cannot contain '..' to indicate the parent directory.

As the message states, you have to enable Parent Folders in IIS configuration for the CRM site.
