In order to run C++ PMI-suite apps (all but Byonic and Preview which are developed in Java), the CPU should support AVX instruction set (this is a hardware specification), which is required to process C++ tensorflow.dll instructions.
This library (tensorflow.dll) was introduced in PMI-Suite 4.x versions, in order to run Machine-Learning models involved in Feature Finder in 4.x versions. In this way, the latest version that can be run without it is 3.11. This is indicated in System-Requirements section on our website (see https://proteinmetrics.com/support-information/#system-requirements)
For users working with Virtual Machines, hardware specifications are usually "easier" to upgrade that those using physical workstations. Please, contact your IT department to see if there is a way to upgrade your device to support AVX instructions or alternatively swap device.
In order to check if your PC supports AVX you can check link  below.  leads you to the app to check it.
