CBT Client 2.2.12


#1

I try install x64 CBT enabled client 2.2.12 ( UrBackup Client 2.2.12-cbt beta(x64).msi )
During installation “Starting service” ended by error “urbackupclientbackend failed to start”

OS: Microsoft Hyper-V Server 2012R2 x64


#2

Can you try the .exe installer?

Has your server all updates installed? Specifically it needs this update to run: https://support.microsoft.com/en-us/help/2999226/update-for-universal-c-runtime-in-windows

You right, after installing all windows updates on Hyper-V Server 2012R2, all working fine.

Hi,

I catch very rarely error. When i backup very often (interval less 1 minute) then server can’t write to same directory because naming only hours and minutes (for example /storage/HV2/181102-1336/)
