When running the 2FA Addin installer on Server 2008 the setup fails almost immediately with the following error message:
Setup was unable to read the Kaseya base install folder from the registry.
Setup cannot continue
Windows Server 2008 can be a 32-bit or 64-bit OS, and IIS can also be running in 32-bit or 64-bit mode. This can cause the installer to detect the incorrect registry path for Kaseya files.
Check the file version of your installer (Right-click > Properties > Details > File Version). It should be at least v188.8.131.52.
On the Kaseya server, open up "regedit" and look for the registry key "vsaPres" with value "c:\Kaseya\vsaPres" at these paths:
If it does not exist, create the necessary path and inside "KServer.Exe" create a new String Value called "vsaPres"
Create these registry key paths if they do not already exist:
