When attempting to save a project back from Microsoft Project (MSP) to CA Project & Portfolio Management (PPM) a target error is generated that includes the following: 
"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
  • Solution 1: Ensure you are on the MSP Driver version & patch that matches the PPM version.
  • Solution 2: If on any versions/patches prior to CA PPM 14.3 patch 10, CA PPM 14.4 patch 6, CA PPM 15.1 patch 3 and CA PPM 15.2, one known reason you can hit this error is due to a defect. See KB000004116 for more details.
  • Solution 3: Do a clean uninstall/reinstall of the MSP Driver (See KB: KB000045862 for the steps)
