@alvinc1,
 
Welcome to the HP Support Community!
 
I assure you I will try my best to get this sorted.
 
In order that I may provide you with an accurate solution, I will need a few more details and I would appreciate if you could, perhaps elaborate on your concern.
 

What is the product number of your computer?
What is the exact issue you are facing?
What exactly you want to install on the computer? 

 
Look forward to hearing from you and you have a great day!
 
Take care.
 
Cheers!
