A common requirement in the standard Development, Test, Train and Production environment setup is the moving of solutions between organisations, and version numbering.
This application can simply be configured to connect to any number of CRM environments (within reason) and it will detect all of the solutions installed, and their version numbers, and show them in a grid. Any instances where an environment does not have the same version number, the solution is highlighted.
To configure it, simply click the Settings button, and then the Connections button to add your connections. On the settings screen, you can enable and disable the connections you wish to view. It should be fairly straight forward.
If you wish to Download it, you can download the Zip file, extract it and run it.
