+### Troubleshooting
+
+If, when you double-click on ORIGAMI.exe and a command window pops-up for a fraction of a second, you might want to try running it from the command line. The easiest way to do it is to follow these steps.
+
+1. Go to the unzipped ORIGAMI directory
+2. In the Windows Explorer, click on the address bar and type **cmd**. This will bring up a Windows command window where you can log issues associated with ORIGAMI.exe
+3. In the command window type in **ORIGAMI.exe**
+4. If its working, a new window should appear and if its not, you will see some error messages
+
+1. PyInstallerImportError
+
+A number of Windows 10 users have reported issues opening ORIGAMI.exe. It typically comes with this message:
+
+    PyInstallerImportError: Failed to load dynlib/dll 'C:\\Users\\USER\\ORIGAM~1.4\\ORIGAM~1.4\\MassLynxRaw.dll'. Most probably this dynlib/dll was not found when the application was frozen.
+    [3428] Failed to execute script ORIGAMI
+
+This problem is caused by a missing C++ library and can be easily solved by installing [Visual C++ 2010 Redistributable Package](https://www.microsoft.com/en-us/download/confirmation.aspx?id=14632)
