BAT if exist %environment variable folder% (System folders)

Question

i'd like to test if %PROGRAMFILES(X86)%\Folder exists but it seems like if EXIST doesn't like environment variables :/

my way would be :

if EXIST %PROGRAMFILES(X86)%\Folder (
    set VAR=%PROGRAMFILES(X86)%\Folder
)

no matter how i try, it always outputs false...

if EXIST "%PROGRAMFILES(X86)%\Folder" (
    set "VAR=%PROGRAMFILES(X86)%\Folder"
)
