If you have tried to program a Mopar vehicle and it would not program or software would not load or progress to programming, it may be related to this issue:
As of July 15, 2026, Mopar has released a new update for WiTECH 2.0 J2534 that impacts compatibility with Windows 10 systems. The updated .NET Framework included with this release is only supported on Windows 11 computers.
Meaning the latest update included a bit of software that only works on Windows 11. Unless a new update is released to use the Windows 10 compatible .NET Framework, you will have to update your PC to Windows 11 or purchase a new computer if your current system does not meet the Windows 11 hardware requirement. .
