PACKAGEGUID
                                        App-V Package ID.
                                        
                                        Optional. 
                                        By default, all Office 2013 App-V packages created by using the Office Deployment Tool share the same App-V Package ID. Administrators can use 
PACKAGEGUID to specify a different Package ID. You can only use the following characters for 
PACKAGEGUID:
                                        
                                            - 
                                                
                                                    0, 1, 2, 3, 4, 5, 6, 7, 8, 9
                                                
                                             
                                            - 
                                                
                                                    A, B, C, D, E, F
                                                
                                             
                                        
 If you use any other characters, the App-V package is created with the default Package ID. Also, 
PACKAGEGUID needs to be 25 characters in length and be separated into 5 sections, with each section separated by a dash. The sections need to have the following number of characters: 8, 4, 4, 4, and 12. For example, 12345678-ABCD-1234-ABCD-1234567890AB is a valid value for 
PACKAGEGUID. This allows you to publish multiple App-V packages of Office 2013 to an App-V Management Server. But, this doesn’t enable you to deploy more than one Office 2013 App-V package to a single computer.
