License reactivation


Recommended Posts



My company is using snomone v4.5.1.1107 on an old xp pro machine. For security reasons we want to install it on an Windows 10 machine.

But I am not able to activate the license key.


I already installed the latest snom 5 version and replaced the .exe with the version. But that didn't work.


Is there a way to reactivate the license key?


Kind regards,


Christian Guillonard

The keys are different between V4 and V5. You cannot use a V4 key on a V5 executable, it will simply not work. We recommend that you upgrade to V5, not only for move to a newer OS, but there are also tons of fixes, including the acceptance of SHA-2 certificates which were not common back in the V4 days (now they are mandatory). Windows XP was also a great OS in the old days, but is outdated these days.
