G'day
Trying to update a customer of mine from E8 to E14 and get the Launch4J error message.
Have deleted preferences.txt in ..\roaming\energia Still got error.
Copied over preferences.txt from my PC , and after an edit regarding sketch dir , it failed.
Turned off my WIFI in case Energia was getting trapped there. It still failed.
Will try E13 and see if that makes any inroads.
One suspect fact is that the customers PC has only 1G memory and cpu is an atom. But as E8 ran ok on think that eliminates the netbook.
