After you hit apply, then ok, the little black square usually persists. Ensure you have admin permissions to do it - the little square should be visible, however.

I have admin permissions, but for some reason the black square persists.

Do you have an antivirus? Add to the list of exceptions, if so.
Also make sure your folder is not set to read only; you can do when right clicking the main folder's properties.

I added the program to the exceptions list, but I can’t change the read only property of the folder, When I do that the  folder just put back the "read only" property.

The tiny client doesn’t install the launcher, it just opens for a moment and then just closes and gives me an errorlog (I attached the error log archivee).
