In spite of downloading one of the latest version of 7.5, Iâm completely unaware how to utilize the software to meet my purposes. Iâve XP operating version and want to know whether it is ok on XP or should I instal some other operating systems? Guys, can you explain me how to use that software effectively? Or can you suggest me any other software?
