Install a driver on a vista x64

Hi everybody,

I have a vista x64 installed and i d like to install a driver !
for this i've create with nodepad a inf file with all information
(section).

the message is :
the folder you specified doesn't contain a compatible software driver
for your device. if the folder contains a driver, make sure it is
designed to work for x64 based system !!!!

Here is it my inf file

Code:
--------------------

[MANUFACTURER]
%Acme Corp.% = Acme, NTx64
[Acme]
%Acme Model% = Acme100PS
[Acme.NTx64]
%Acme Model% = Acme100PS
[Acme100PS]
CopyFiles = PSCRIPT5.dll
[SourceDisksNames]
1= %Location%
[SourceDisksFiles]
PSCRIPT5.dll = 1
[SourceDisksNames]
1= %Location%
[SourceDisksFiles]
PSCRIPT5.dll = 1
[strings]
Location="C:\Users\chb\INSTALLATION"
Acme Corp.="MOI"
Acme Model=TOI


--------------------
