When trying to apply an update to the Ghost Solution Suite an error comes up that the prior install can't be found and the update won't install.
Cannot proceed with the installation. No previous installation of Ghost Solution Suite 3.2 is detected on this computer
One of the needed registry keys that GSS RU installers look for may be missing. This was seen when a GSS server was installed to a non default folder using GSS 3.0 and then upgraded to 3.1 and then 3.2.
In Ghost Solution Suite (GSS) 3.2 this has been reported while trying to apply the 3.2 RU3 update but the situation isn't limited to only the 3.2 RU3 update.
The following registry key needs to be in place on the GSS server. It is a registry string named InstallDir and the path to the install directory similar to C:\Program Files (x86)\Altiris\eXpress\Deployment Server
The screen shot below is from a default installation adjust the registry settings as needed to reflect the GSS install location.
