The parameters passed to the exe should be separated by spaces not commas. See mskb #Q109612.

>Leave off the dash, and seperate parameters with commas. For instance, you should be able to run the below by using:
>
>c:\ac\account.exe L
>
>I think that all parameters passed this way come in as character, so you may have to convert to other data types if needed.
