x64.nsh not working

I have encountered a piece of code in the web...
I have 64.nsh in my machine and as an example I have included in my code the following:

${If} ${RunningX64}  
MessageBox MB_OK "running on x64"  
${EndIf}

And it returns: 

!insertmacro:
_If  !insertmacro: macro "_If" requires 4 parameter(s), passed 2!

Could you help?
Thanks in advance!

Solution

  • Having the file on your system is not enough, you need to include the file in your code:

    !include "x64.nsh"
${If} ${RunningX64}
MessageBox MB_OK "running on x64"
${EndIf}
