Problem with Share Foler and Grant Complete Access

[crustyzz]

when I share a folder after Applying Install, I set Access Control to Complete with the command Set Access Control,
Object Type = Share,
Operation = GrantEveryone Total Contal.

I appears that nobody can acces my shared folder.

I noticed that when I manually add the Gest account in the security tabsheet of my shared folder, and give it total control. Evereybody can access to the shared directory.

Then I added a Set Access Control command in my script just after the grant Complete Access
Object type = Share,
Operation = Set Chosen Users whit access Rights,
Users Accounts/groups= Named User Account/group = "Invité" (this is
the french account for guest)
Access Right = Read + Write

But there is no Invité with total control in the security tabsheet of my shared folder and nobody can access to it.

Does anybody have an idea to help me sharing a folder?
I just want everyone access to my shared folder.

Thanks a lot
