You can do this provided you use the API protection method with cm.dll.

It is also theoretically possible to do it with the Shell method provided you do not use the ARP (Advanced Runtime Protection) option. With this method, it is a bit fiddly because you need to

1. Rename each exe file to a common name (e.g. common.exe).
2. Protect each of these common.exe files.
3. Rename them back to their original names.

We recommend that you use the cm.dll rather than the Shell Method.

Remember that all the programs will be sharing the same execution count, expiry date and so on. If you want to keep separate counters then you could do so in the Secure Data Area.
