problem with aocl install

Hi,

I tried to compile main.cpp from an example provided by Altera (vector_add), and the compilation failed. it seems the compilation failed because ths FCDs wasn't installed.

but when i try to install the drivers (with aocl install) i get the following message :

"error: cannot open service control manager

make sure you are running with Administrator privileges"

how can i issue this problem ?

thanks for your help
