+## no module dispatch
+
+I was trying to run acquisition on a win10 PC (phy-lmx2cpu) with a py3 PYME install.
+Got an error that a module named dispatch was missing.
+
+Fixed by
+
+	conda install dispatch
+
+Note that I searched for dispatch first:
+
+
+	conda search dispatch
+
+which printed:
+
+```
+Loading channels: done
+# Name                       Version           Build  Channel
+dispatch                         1.0          py27_0  david_baddeley
+dispatch                         1.0          py36_0  david_baddeley
+dispatch                         1.0          py37_0  david_baddeley
+```
+
+This seems to indicate this is a module supplied by David's channel only.
