DXO 5.4 to 5.5 - update error

Hello,

Windows 11 25H2 all update ok.

During setup (update 5.4 to 5.5) i have error :

“A problem has been detected in this Windows Installer package. A program required for this installation could not be run. Contact your technical support or the package publisher”.

Restart computer, re-download, run as administrator - same error.

Need some help please.

Sincerly,

Fred
