VMware vCenter Server 6.5.x VMware vSphere Update Manager 6.5.x
Cause
This issue occurs due to special characters in the users password.
For example, there may be a semicolon or similar special characters in the password of the account which is used to install update manager. The semicolon is used as a separator when processed by the vciInstallUtils.exe command.
Other problematic characters maybe non ASCII or:
~ tilde
^ caret
\ backslash
Resolution
Currently, there is no resolution.
Workaround: To workaround this issue, remove the semicolon or special characters from the password of the account which is used to install the update manager.
