We have a mix of GW 6.5, 7.0 and 8.0 clients. We would like to start pushing out the GW 8.0.1 client. What is the best way to manually uninstall each version before installing the GW 8.0.1 client? We have tried using the CleanIt tool. It seems to do a great job of removing the GW 6.5 client but we run into problems when trying to remove the GW 7.0 and 8.0 client.

We would like to remove all the files and registry entries from these earlier versions before installing the GW 8.0.1 client.
