Hi There,
One of our customer had this issue today, And we sorted it out.
Step- 01 Always make sure The agent is on the right version. (Ex: Windows 8 will support only latest versions, 8.8)
Step-02 If you have the right version then first install the Framework.pkg
Step-03 Now install the VSE (Make sure you have the compatible version for the windows that you are using)
If everything was ok, Then the update for the VSE should be up and running.
Thanks,
Humaid
