In rare cases IronCAD crashes can happen because of a specific problem on a computer, like AntiVirus on that computer or the hardware on that computer. The debugging tools help the IronCAD R&D team determine what is causing that specific computer to have problems, so they can help fix them. These instructions show how to install the debugging tools.

How to debug an IronCAD crash:

1 - Start the WinDebugger (Start, Programs, Windows Kits, Debugging Tools for Windows (X64), WinDbg (x64)
2 - In WinDbg,  go to File, "Open Executable"
3 - Browse to ironcad.exe (typically in C:\Program Files\IronCAD\IRONCAD\20xx\bin)
4 - Click No to the question "Save information for workspace"? (if it comes up)
5 - Click View, Call Stack
6 - Press F5 to start. Note you may have to press F5 several times to get IronCAD starting, the bottom of the WinDebugger Command window should say "Debuggee is running".
7 - Let IronCAD attempt to run as usual.

Then when the crash occurs save and send the window text in WinDbg:

1 - Select the Command window
2 - Go to the Edit menu, "Write Windows Text to File..."
3 - Select the Calls window.
4 - Go to the Edit menu, "Write Windows Text to File..."

Then send those text files to your local IronCAD representative who can use them to help diagnose what is happening on your computer.
