Hi Ed,
The anti-virus folks were back to me very quickly. Confirmed it was a false positive and your installer package was "whitelisted". Webroot has not had a false positive problem for me in over a year. The package hash value is in their system now
This was first time I have tried this program and will have a bit of a learning curve figuring out what files I need for which purpose... looks like the online help file is a version behind, but probably very usable.
Thanks,
Jack - KD4IZ
