I downloaded and ran the Windows installer for v8.4.4 as the administrator. I installed the update into the existing C:\VarAC folder. Unlike the previous version of VarAC, whenever I change a setting in VarAC and try to save the settings, I get a message that VarAC doesn't have write permissions for this folder. The only way to be able to save the new settings is to terminate VarAC and restart in administrator mode.
