Hello. I know this has been previously answered, but I have a customer who has renewed his maintenance (late) and cannot update their 3cx. Currently they are on v15.5.9348.3 and can't uprgade

The download link offered by YannisH_3CX in this post is not available anymore and gives a 404 message.

I can't seem to find any way to update the customer.

How should I proceed?

Hi what license is it , Free? Commercial ? STD ? PRO? Local ? Cloud? Debian? Windows?
If commercial , you should take a complete backup, desinstall and reinstall 3CX up to date V15.5 SP6 and then backup once more and reinstall V16

link for V15.5

Hi Stefan,
I think this should do just fine.. I couldn't locate the link!! I'll visit the client either today or tomorrow and let you know if it worked.
Thanks again!!

Hi!
License is Standard Perpetual 15.5.9348.3 on an HP server running Windows Server 2012 R2.

I'll try the updater and see how it goes because as it stands, the system cannot reach the update server and cannot validate maintenance or updates or anything!

If I can get that to work, I can handle the rest.

Thanks again!!

...also, do you think this is why it shows maintenance as expired in the customer's 3cx admin, eventhough it has been renewed (allbeit a super late renewal but within grace period) ??

old versions not on SP5 or v16 cannot update this information anymore.
therefore best to use the offline v15.5 updater and then all data will be pulled.
Once on v15.5 U6 update further to v16.
