+====== Manually Creating a Memory Dump (DMP File) from an Unresponsive Rhino for Windows ======
+Back to [[https://wiki.mcneel.com/rhino/faq#display_problems|FAQ]]
+[[https://wiki.mcneel.com/rhino/manual_rhino_dmp_mac|Link]] to the Mac DMP Instructions.
+===== Problem: =====
+There are times when Rhino may become unresponsive and appear frozen. Despite your efforts, there doesn’t seem to
+be anything that you can do to bring it back.
+Rhino may have crashed and has not fully shut down.
+It just sits there on your screen.
+In these cases, it is possible to manually create a “memory dump” or **DMP** file from
+the Rhino in its current condition.
+Rhino developers can then use the DMP to discover where Rhino got stuck and why it
+appears to be frozen.
+===== Steps to Creating a DMP File for Support =====
+The following steps outline the process for manually creating a dump or **DMP** file.
+. Once you realize that Rhino is in an unresponsive state, start the **Task Manager** by right-clicking
+on the **Task Bar** and select **Task Manager** in the popup menu that appears.
+{{:rhino:dmp_manual_01.png?600|}}
+. Look at the **Task Manager** window, make sure the **Processes** tab is selected, and locate the
+**Rhino** process. Right-click on the **Rhino** process and select **Create dump file** in the
+popup menu that appears.

+**Note:** If you do not see the dialog that has the tabs **Process and Performance**, pick **More Details** at the bottom.

+. Windows will start creating a dump file in your temporary folder on your system.

+. Once Windows has finished creating the dump file, you will be shown the name and location of
+the file. Next, select the file to copy and paste.
+{{:rhino:dmp_manual_04.png?600|}}
+. Next locate the file **RhinoCrashDump.DMP** on your system in **File Explorer**. ZIP or compress the file before uploading. Note: we do not need the RhinoCrashDump.3DM.)
+. The **RhinoCrashDump.DMP** file will be too big to attach to an email. Please use our upload system [[https://www.rhino3d.com/upload|here]]. Use **tech@mcneel.com** as the recipient. Include the details in the note field about what you were doing in Rhino when the problem occurred.
