A dynamic SKU manager creates versions of programs with different feature sets without a recompilation of the products. Features are enabled either before shipping to a user, or after the user has a partially enabled product. A brand module creates an encrypted value for each version which is unique to the machine on which the program is installed. The encrypted value contains an identifier, a date, and a machine unique name. A query component is called by various components of the program to obtain information about features and capabilities of a currently installed program. It also keeps track of which SKUs are available, and need not be recompiled if no changes have been made to the available SKUs on the machine. The query component is dynamically loaded and unloaded each time it is needed.
