Every upgrade causes After Effects to stop loading properly. It gives error messages. I have contacted support on this on at least two occasions. The technician fixed the problem but it recurs with every update, either Adobe or Nvidia updates. This happens consistently. It seems to me that a consistent problem is one that can be isolated and fixed, yet this has not happened.
With hopeful respect,

Without system information nobody can even begin to help you. Based on your description you seem to not be installing updates with sufficient user privileges and your system gets stuck on installs that technically never finish or system restore is rolling back files. anyway, as I said, we need a lot more info.
