I was getting the error ‘Error: Unable to find fileDFUI.exe please verify your install is correct.’ when trying to run an Azure project locally. MS have a rather hefty workaround here which I really didn’t want to use (especially since the error will come back after a while).
An easier workaround is to backup your ServiceConfiguration and ServiceDefinition files and delete the Azure project from your solution, also delete all traces of the Azure project from your solution directory.
Next add an Azure project to your solution (don’t add any roles). Add the roles manually using your existing projects (right-click on ‘Roles’ within the Azure project and select ‘Add > <X> Project in Solution’.
Restore your backed up service config files and you should be good to go!
