["Skip User Account Control Warning" gives an error]

Hello,

 

I run CCleaner 5.01.5075 on a win 8.1 System.

I don´t know, if it is a "admin or local account", sorry I even do´nt understand that question (in another post).

I just installed the program.

 

My problem is, that after each new start of my PC the uac asks if I want to run ccleaner.

 

So I learned to know the checkbox "Skip User Account Control Warning", but it  doesn´t work on my system.

 

The error message is "falscher parameter".

 

Can anybody help me?

 

Thank you in advance,

 

Ralph
