registry

Hello,

I was trying to make a shell command for a new file type i was creating,

i created a registry key that led to the file that was used for the

it was something like this:

A file something.exe was stored in %systemdirectory%
and the registrykey (string, default, etc) said
%SystemDirectory%\something.exe "%1"

My problem was that when i tried to use the command i had a message box

said:
Somedir\something.exe
access is denied

and i tried several combinations for my registri to work, the only thing i
could do was to give it the real path something like
c:\windows\system32\something.exe "%1" but that isnt useful.

Well, thanks in advance, just for reading this, luck to you all..
