DPP4 Crash after update

[apk2]

I have used DPP4 for many years. When I upgrade to either V16.11 or V17.10 from V12.60 it immediately crashes on open. If I uninstall V16.11 or V 17.10 and reinstall V 12.60 it works. I have cleaned the registry after uninstall etc etc. Windows 10, intel i7, 32GB RAM. All other software (LrC, PS, DxO, etc.) work fine.

Any help here?

[apk2]

No joy.

If you have a current version of DxO Nik Collection they let you download a free version of DxO Photolab.
