I am attempting to script the addition of VSE 8.8 to ePO 4.6.4. I have been successful in checking it into the repository using repository.checkInPackage, but I am unable to get ext.install to work. The error I get is:
Error setting parameters for command: ext.install
the string I'm passing to ePO is essentially this:
https://localhost:8443/remote/ext.install?extension=<path to extension zip file>
I am doing this via Powershell using the System.Net.WebClient interface
Any ideas on where to look to correct this problem?
