Ok, I’ve tried it now with a fresh and clean Windows Server 2008 x64 VMware virtual machine and it seems to be like I assumed: The account on which you want to install Antivir PE and which read rights you deny has to be an administrator-type account (at least until the installation is complete). Otherwise (with normal user rights) it definitly didn’t work.
Plus, I’ve tried to install AVG Free and Avast Home and here are the results:
– The installation of Avast Home works with this registry tweak too
– The installation of AVG Free doesn’t seem to rely on the “ProductOptions”-Key so in other words: It won’t work like this
So it’s now at least 2 of 3 free antivirus softwares which work with Windows Server 2008 🙂
