Assistant with Action - Uninstall Not Working

Folks,

It may sound very simple, but bigfix keeps failing to run this line.

waithidden “{pathname of system folder & “\msiexec.exe”}” /x{{D2372F87-7DA2-47F7-A102-AF2181B8EAA2 } /qn

It may be a forum thing, but {D2372F87-7DA2-47F7-A102-AF2181B8EAA2 } has an apparently rogue space at the end
