Insufficient disk space, Tu7 error Acrobat Standard 2017

Purchased Adobe Acrobat Standard 2017 today from a retail store. Followed the instructions to get a serial number, then followed the instructions to download the program. When running the installation about 2/3 thru a message box pops up that says "Insufficient disk space. Please check minimum requirements and free up disk space to try again", when you click OK another message box with "tu7" pops up. Tried uninstalling Acrobat Reader(only other Adobe program on the computer), still didn't work. Tried extracting to the desktop, program files, downloads, all with the same results. Tried using Chrome and Edge browsers and downloading the Acrobat Standard 2017 and Standard DC installers. Turned off anti-virus software and nothing has worked so far. Computer is a month old with hundreds of gigs of free space. Help please, was hoping this would be a basic, simple install.
