Hi Nicole,
You can also get it from the registry.
On a 64-bit machine, the license key is under:
HKEY_LOCAL_MACHINE/SOFTWARE/Wow6432Node/SAP BusinessObjects/Suite XI 4.0/Crystal Reports/Keycodes/CR Dev
The string value, also contains a 'Date' towards the end.
The Key is everything to the left of the ':'
You can also call sales at 866-681-3435.
