Techniques for implementing a systematic installation of software extensions are disclosed. In some embodiments, a computer system performs operations comprising: detecting a request to open a target file of a base computer program on a client machine, the target file residing on a server machine; determining that the target file includes a target version of a software extension; determining that a user of the client machine is part of a user group having administrative permission for the base computer program; determining that a systematic installation criterion from a group of systematic installation criteria is satisfied; and installing the target version of the software extension on the client machine based on the determining that the target file includes the target version, the determining that the user is part of the user group, and the determining that the systematic installation criterion is satisfied.
