I have done that already however the error I am getting may be related to the Helix framework and the joomla 4x as well as VM 4x. The developer doesn't list these updates in their site, they have Joomla 3.9x and VM 3x version listed as well as T3 framework.
Hove you try to install this package as a test? This would be helpful and if you can successfully install it then my server should have some settings I am not aware of.
I use hostgator share hosting.
Thanks
