Hello imafifer264, I'm Didi, an independent advisor.
Firstly before attempting another installation turn off any antivirus software.
Go to File Explorer, on the left pane click on the disc drive that is used to read your Printmaster disc, right click on the .exe file that is used to start the installation (probably setup.exe, installer.exe or something that looks like it) and select the 'Run as administrator' option from the drop down list.
Does it helps ?
Regards,
Didi
