When selecting "Yes, install and activate the 'CardioLog Analytics' SharePoint Feature" in Step 2 of the Configuration Wizard, the following error may occur:
There was some problem with the installation or activation of the 'CardioLog Analytics' SharePoint Feature:
stsadm addsolution error: Object reference not set to an instance of an object. The Solution installation failed.
This error is raised when the CardioLog service account has insufficient permissions.
Please confirm that the CardioLog service account is SharePoint farm administrator, a local administrator on all SharePoint servers, a "db_owner" on the SharePoint config database, and that it has all required permissions, then run the Configuration Wizard when you are logged on to the server with the CardioLog service account.
In case you would like to try a different user, change the account in IIS (the identity of the CardioLogApplicationPool) and for both CardioLog windows services (the logon account for CardioLog Scheduling Service, CardioLog Diagnostics Service).
