If you are experiencing that Datashop crashes before it even displays its splash screen and you get a message from Windows that the application crashed then the cause is probably restrictions on the user's permissions.
The possible scenario is that you are trying to make an installation without running the Acinta installer, e.g. a network installation. The installation works fine for you (because you use a classified account, e.g. Administrator) but it fails on end-users' PCs.
SOLUTION Right-click on the exe-file or shortcut and choose "Run as administrator...". You only need to do this once. Next time you open Datashop it will work fine.
