Blocked to set affinity [Solved]

[Bilbo]

Well, lately my GTA SA game has started to "lag" pritty badly. Well, don't know about others, but I found out through the Task Manager, that the game is guided to use only one of the available processors I have. (Dual Core). Well, of course I tried to set the Affinity level for both processors, but it gives me this following error. Setting the affinity on other processes is possible though. Any thoughs how to pass this?

Uhm, thats really weird, did you try to start singeplayer, not through SAMP and then change the affinity?

Nevermind, solved.

You have to use the built-in Administrator to set the affinity for some processes.
(requires to active and log into the built-in administrator)
