If the game crashes or freezes when running on Windows, you can help us to debug the problem. If you have Visual C++ installed then you can use its debugger. Otherwise you should try these instructions to run the free WinDbg? tool:

• Install the ​Debugging Tools for Windows. (In the Windows SDK installer, you can disable everything except the first "Debugging Tools for Windows" option.)
• Run WinDbg from the Start menu (in "Debugging Tools for Windows", or if you are on 64-bit Windows then "Debugging Tools for Windows (x64)").
• "File" menu -> "Open Executable".
• Browse to the location where you installed the game, and open pyrogenesis.exe in the binaries\system folder.
• If you want to debug the Atlas editor, put "-editor" in the "Arguments" box before clicking "Open".
• If it asks to "Save information for workspace", say yes.
• Enter the following commands: (the last step may take several minutes the first time you do this - wait until the "*BUSY*" prompt goes away)

  .symfix
  .reload /f
  

• "Debug" menu -> "Go".
• If you are on 64-bit Windows: The game may not start immediately, and the WinDbg window may say

  (690.8c8): WOW64 breakpoint - code 4000001f (first chance)
  First chance exceptions are reported before any exception handling.
  This exception may be expected and handled.
  ntdll32!LdrpDoDebuggerBreak+0x2c:
  770b0f3b cc              int     3
  0:000:x86>
  

  In that case you should do "Debug" menu -> "Go" a second time, and then the game should start up.
• You may want to switch the game from fullscreen to windowed mode (press alt+enter while running it) to make it easier to see to the WinDbg window.
• When the game has failed (frozen or brought up an error message), switch to the WinDbg window and "Debug" -> "Break".
• If you are on 64-bit Windows: Enter the command

  !wow64exts.sw
  

• Enter the command:

  ~* kp
  

• If it shows a "*BUSY*" prompt, wait for that to go away (might take several minutes the first time you do this).
• Copy-and-paste the output into some kind of pastebin service like ​this and post the link to it.
