Versions: 6.x/7.x
When working with Risk for Project files, there's a possibility Excel crashes causing errors like "Automation Error: System Call Failed" when running or ending a simulation file.
After troubleshooting with some of the affected users, the problem has been discovered after Excel 64-bit doesn't talk to MS Project causing the error described, and as a workaround, installing Office 32-bits has solved the problem.
If these steps will be followed it is important to make sure you see: Removing Outdated References to Office from the System Registry to remove any outdated keys from previous Office installations, this way the Excel and MS Project can communicate properly.
