Hi all,
Just reporting that it appears the Mirage Management Server doesn't like you using service accounts with passwords that contain 'unusual' characters.
When installing Mirage Management Server where the service account password was t;84-};,OD>,}33 the following error occured (around the point after services have started and it's installing default BI policies):
"Quiet exec failed: Given argument could not be parsed"
After changing the password to a random string of alphanumeric characters, the installation completed successfully.
Hope this helps.
