Installation problem

Hi I am having problems with push installation from Avast Small Office Administration dashboard
I do an autofind of new computers and that works
Run the deployment and I get an error message reading

Hostname (The system cannot find the file specified [2])

These have been done in the same way as many other machines - many of them Windows 7 but I cannot see what’s different - Any help will be appreciated.

I have had this happen to me a couple of times. I found when this happens if I look at the jobs history that the Update Server Definitions job failed for some reason. I run the job, make sure it succeeded and try the Install again. This always works for me.
