Hi Hamza Ali Abbas Khan,
As you have already used Optisystem for 30 days and its trial version is over.
You can’t use optisystem for same computer, so try to use on another computer if you have.
Yeah, you can download optisystem for three times but it doesn’t mean that you could use optisystem for 3*30= 90 days.
it is only for the case in which your download fails, you could download the files upto three times.
Hope you could understand.
Seeking your response
