open Step files with Alibre Win7 on doubleclick

[ASP]

does anyone knows how to set Win7(64) to open .STP, .STEP and others on doubleclick with AD ?

with WinXP (and 12.1) this was not a problem - doubleclick it, and choose AD from the list of programms,
but with Win7 AD is not in the list and if I browse to and choose AlibreDesign.exe it doesn't accept it (nothing happens)

nobody knows ?

so after a deep research I found out that the open command for the AD Application is registered wrong:
in Registry Editor:
Computer\HKEY_CLASSES_ROOT\Applications\Alibre Design.exe\Shell\Open\Command
set the value from
"C:\Program Files (x86)\Alibre Design\Program\Alibre Design.exe" "%1"
to
"C:\Program Files\Alibre Design\Program\Alibre Design.exe" "%1"

and Alibre then can be set as a default programm...
