As stated by Microsoft, "Beginning with Windows 10, version 2004, all new Windows 10 systems will be required to use 64-bit builds and Microsoft will no longer release 32-bit builds for OEM distribution." (https://docs.microsoft.com/en-au/windows-hardware/design/minimum/minimum-hardware-requirements-overview)
The current default for Maptitude is 64-bit and we will imminently be discontinuing the 32-bit build. In addition, none of the routing tools work in 32-bit Maptitude, including the Routing & Directions manager and Drive-Time Rings.
Given this, we are encouraging all 32-bit users to upgrade their PCs to 64-bit Windows.
However, if you have a particular situation that requires 32-bit Maptitude we can provide it on a by-need basis. Please contact us at firstname.lastname@example.org and we would be happy to discuss your options with you.
