perl path on windows

[g-i-o-r-g-i-o]

When try to run "perl" from inside vim (or gvim) on Windows 8.1 I get the error message "(possibly default) Perl Interpreter 'c:\Perl\bin\perl.exe' not executable."

Perl executable is in "d:\sbin\perl\perl\bin\perl.exe", how do I force Vim-Perl to find it.

I've already put in my vimrc this statement
let g:Perl_Perl = 'd:\sbin\perl\perl\bin\perl.exe'
