In this tutorial, let me tell you about How to Fix an Error on Reporting Services “The report server installation is not initialized” ? I had an undertaking for restoring the Reporting Services database from a live situation to a test domain.  Directly after the effective restore, I took  opening the Report Manager site and I was given the error "The report server establishment is not introduced. (rsReportServerNotActivated)". As you can see on the following picture:

SOLUTION

This is a result of the  mismatch in the encryption key. To alter this, either restore the encryption key from the live environment or erase the encryption key from the restored reporting administrations database.  The restoration or cancellation of encryption key could be possible by utilizing the Reporting Services Configuration Manager.

I hope this tutorial works for you!
