can't install nvidia driver

[eggie99]

hi all

 

Tried to install nvidis driver package with open gl nvidia inject

and nvidia driver pack. I deleted open gl and went to replace it

it keeps saying you are not allowed to perform this no permissions set

 

tried all sorts but couldn't do it and had to reboot the pc and now all

I get is apple screen with spinning wheel nothing else

 

Any help how to sort this without fresh install

 

Thanks
