setiface.dll error 126

I had an older install of AES and Clients, that server died one day. So I re-installed on a new server and went to deploy the clients on all the computers.
I have a about 30 out of 200 that are giving me this error when I try to deploy

05/12/15 08:33:44: InstSvc begin
05/12/15 08:33:44: avast! Remote Install Service

05/12/15 08:33:45: DSA_FileVerify C:~AVINSTL\setup.exe error
05/12/15 08:33:45: InstSvc end 0

Any ideas?
