When I click on the setupeng icon evrything goes fine, until it gets to the service part of the installation progress, and then it stops and won’t go any further. I have tried uninstalling and reinstalling several times to no avail. Can someone please help?
Hi Jjphelps1 and welcome,
Please, give more information:
Which Avast! release are you trying to install?
Wich OS is on your desktop?
Are you running an another AV?, and in that case have you uninstall it before Avast! install?
Thanks to help us 
Can you see some error messages?
I’m getting the same problem trying to install Avast 4.6 SBS Edition on a Small Business Server.
There isn’t any other virus protection software on the machine.
During the installation process I’ve ended up with a dialog box with “Installation progress” written in large letters across the top and the word ‘Service’ in the middle, there’s no progress bar, the only other thing on the dialog is a cancel button.
I have a feeling there is already a virus on this server (but I don’t know what it is) and are wondering if this could be stopping the installation process.
What should I do?!

This would probably be better on the avast! 4 Server Edition forum http://forum.avast.com/index.php?board=8.0, not the avast! 4 Home/Pro forum where it is likely to be lost among the home/pro threads.
