Issue
I have a project that built in Unity Pro version 7.0 cannot open in version 8.0. Error indicates full memory card.
The error on build is:
PLC memory card full! Please check the memory consumption screen and the associated online help for further assistance.

Product Line
Unity Pro

Environment
Windows 7, Windows 10

Resolution
Version 8.0 uses 6 kilobytes more overhead memory than version 7.0.
A larger memory card or application revision is required.
