Upgrading Qlik Sense Enterprise on Windows fails with a generic error message:
An error has occurred
For detailed information see the log file
The Qlik Sense Repository Database service is no longer installed after the failed installation.
This means that the database password validation did not complete and a partial rollback has occurred. This has removed the database software, but it has not removed the database itself.
The database password is normally password is checked before the upgrade process begins, but under some circumstances, such as the database service being stopped, this check does not occur. Once the new version of the database software is installed it will attempt to open the database as part of the install verification process and will fail. This then prompts a rollback of the database software and removing the new version.
Resolution:
Reinstall Qlik Sense. (Uninstall, Reinstall)
During the uninstall process, do not remove the certificates or database.
Once Qlik Sense is uninstalled, you can proceed to install the desired upgraded version of Qlik Sense, the installer will detect the existing database and request the password, if it is from an earlier version the installer will make the necessary changes as part of the installation process.
Environment:
Qlik Sense Enterprise on Windows
