How can you solve a problem with Manga Studio EX 4.0 when you click on Install materials from Disk it shows to you the message The system cannot find the file specified?

If it keeps failing when trying to install the materials then the way around that is to manually install them. Start by browsing the CD open the Material folder, open then settings folder, then select copy the 3 folders in there. Then browse the drive you installed Manga Studio on choose Program Files, then Smith Micro, then Settings, paste them there. You might have to do it for each folder if it won't let you choose all 3.
