+### Troubleshooting
 
-NikonTi2 should then appear in the Hardware Configuration Wizard.
+- If `NikonTi2` only shows as `NikonTi2 (unavailable)` in the config wizard, ensure that you have moved the `Ti2_Mic_Driver.dll` into the same directory as the `mmgr_dal_NikonTi2.dll` library and have *not* renamed `Ti2_Mic_Driver.dll`.
+- If the `NikonTi2` folder is available in the config wizard, but you only see the `*Ti2-Simulator` device available:
+   - Make sure that your microscope is powered on and connected to the computer (you may have to restart micro-manager if you powered it on after starting micro-manager).
+   - Make sure the SDK can control your microscope *without* going through micro-manager, for example by running `C:\Program Files\Nikon\Ti2-SDK\bin\Ti2Sample.exe` and confirming that your microscope responds to button presses.
+   - If all goes well, you should see one or more devices in addition to the Ti2-Simulator, for example a Ti2-Eclipse microscope may appear as `*Ti2-E__0: Nikon Ti2 microscope`.
