Hi Appack14,

To add to hrs2cool ,when you make changes in MSI tables,Orca saves only that particular table and other tables are not saves when complied and this would not increase the MSI size where in using Install shield editor the size would go on increasing based on no of times you compile the MSI.

2nd reason for using Orca is its easy to see what changes you have made in a MST or even to open a MSP file its easier to see the details,


Validation by Orca would also have a upper hand as they would have the latest .cub file(Provided you have the latest version of Orca).


Hope this helps
