With the latest version of App Volumes 2.12.1, you don’t have to uninstall the older version of App Volumes Manager. The latest App Volumes Manager 2.12.1 installer takes care of uninstalling, fresh-install and retain all the configuration details and settings automatically for you.
During the upgrade I encountered the following error:
“Error 1303. The installer has insufficient privileges to access this directory: C:\Program Files(x86)\CloudVolumes\Manager\log. The installation cannot continue. Log on as an administrator or contact your system administrator.”
In our scenario we have VMware vRealize Log Insight Agent installed on the App Volumes Manager VM’s which is doing Syslog. The Log Insight agent captures the logs(production.log) inside the folder “C:\Program Files(x86)\CloudVolumes\Manager\log”. As the service is in the running state, it didn't allow the folder to delete and left a ghost folder on the filesystem.
After going into the services.msc and stopping the VMware vRealize Log Insight Agent service and click Retry, the setup manages to complete the upgrade successfully.
I hope this workaround helps you during your upgrade if you encounter a similar error message.
