# SpatialExplorer-Compatibility

SpatialExplorer installs two executables, a standard version and a compatibility version:

Most users should run **SpatialExplorer.exe**, however users with older workstations or complicated IT screening services can run the **SpatialExplorer-Compatibility.exe**. If **SpatialExplorer.exe** does not launch properly, consider running the compatibility executable.

{% hint style="warning" %}
&#x20;The compatibility version will typically process slower than the standard executable.&#x20;
