Due to cbbackup/cbrestore trouble in the version 501, I’m trying to upgrade my server CE 501 to CE 511, firstly on my windows 10, as a test platform, before doing it on my windows server 2016.
I stopped the couchbase service and sync gateway service too.
I lauched the installation using the file couchbase-server-community_5.1.1-windows_amd64.msi, I let the default location folder, and during the copying files step, I have a Rollback due to an error, without more information.
What can I do ? Is there an installation log ?
