How to judge user's OS is x86 or x64?

[keitaro0130]

Dear All,

 

Could someone tell me how to judge user's OS is x86 or x64 through inf file?

 

I would to make a 64bit ActiveX control installation, but I do not know how to judge the OS's version.

 

The following is my code:

 

 

[version]
signature=$Chicago$
AdvancedINF=1.0

[DefaultInstall]
CopyFiles=MyFiles
RegisterOCXs=RegisterOCXSection

[DestinationDirs]
MyFiles=16422,NVR\Playback

[MyFiles]
Test.ocx=Test.ocx

[Test.ocx]
file=thiscab
FileVersion=1,0,0,0
RegisterServer=yes

[RegisterOCXSection]
"%16422%\Test\Test.ocx"
 

 

By the help of Google, I find the the website:

https://social.msdn.microsoft.com/Forums/ie/fr-FR/32ec4e8f-cded-4f39-b57b-bea2222fdb92/how-to-create-x64-activex-controls-for-internet-explorer-64-on-vista7-64-editions-?forum=ieextensiondevelopment

 

The web said I just need to set "file=thiscab" in the section, the 64bit could work.

 

Could anyone tell me what's wrong?

 

Thanks.

 

Regards,

Youlin
