A computer system and method for installing a software product. A computer system includes a client coupled to a server. The client obtains an installation package of files to be used to install the software product and for each file, determines if there is a later file version available. The client creates a temporary folder. For each file, if a later version is not available, the client adds a link to the temporary folder that refers to the file in the installation package and if a later version of a file is available, adds a link to the temporary folder that refers to the later version of the file. The client executes an installation operation on the temporary folder. For only those files for which a later file version is available, the client may add links that refer to files downloaded from a server and stored in an update folder.
