Writing unsupported AppCompatFlags value on 64-bit Windows

[Ptitus37]

Hello, my dear,

I would like to know how to create the Layers directory via NSIS
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers]

On a blank machine this directory does not exist and I put this in my script
WriteRegStr HKLM "SOFTWARE\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers" "C:\application,exe" "~ RUNASADMIN WIN7RTM"

and it does not create it.
You can come to my help.

Is the application you want to set the appcompat flag for 32-bit or 64-bit?

You are not really supposed to set these flags, the user is supposed to set them. You as a application author should just fix your application so it does not require hacks!

Yes, our application is concerned with running Windows10 usually in 64bit.
And I wish to automate the registration of these rights on our executables when we install a new machine in our customers.
Just to avoid having to manually right click on the executable and run in Windows7 and admin compatibility

So you are choosing to ignore Microsoft's advice and set a value you are not really supposed to set instead of fixing your application?

To set a compatibility flag for a 64-bit application you must detect if you are on 64-bit Windows with the macro in x64.nsh and if that is the case you can call "SetRegView 64" to change to the 64-bit registry view.
