Question: High Sierra Update stuck while installing

Dear Apple Community

I got a question regarding the High Sierra update.

I downloaded the update and wanted to install it. After the restart it showed an error message that not everything could be installed.

So i clicked install again and now it's stuck while calculating (approximately an hour).

So now I wanna now what I should do now? Restarting? I don't wanna risk that the macbook isn't booting anymore then.

I hope somebody can help me

MacBook Pro 2017 Two thunderbolt 3 ports, 2.3 GHz Intel I5, 8gb RAM , 256gb
