There is a BUG in Wscript (TargetPath).

Try the command line for ms Access shortcut like:
Code:
"path access.exe" "path to accessdb" /params "path to mdw" /params2
If you use wscript all backward slashes becomes forward slashes for the params part.

Did not find a workaround yet.
Also
Code:
char(47)
does NOT do the trick.
