To do an unattended or silent install of a CETDesigner.msi, execute this command in Window's command terminal:
msiexec.exe /i “CETDesigner.msi” /qb CET_VERSIONID=64-bit TRANSFORMS=:InstanceId01
The reason for the extra arguments is that CET supports parallel installation of multiple instances (with different version-id).
This is the Version-id used for the installation. Default is “64-bit”, but beta versions have different version id:s. Usually the version id will be included in the file name of the msi, prefixed by a hash-sign, for example "CET 18.104.22.168 64-bit#MyBetaVersion-64-bit.msi" where the version id in this case is “MyBetaVersion-64-bit”. When installing the msi using the UI, the version id after the hash-sign will be automatically used, but for silent install it must be specified manually using this argument.
This argument can be anything between “:InstanceId01” and “:InstanceId20” and must be unique for each installation. When installing msi:s from the UI it will be automatically increased for each installation so the first one is “:InstanceId01”, the second one is “:InstanceId02” and so on. But when installing silently, it must be manually set to a value that hasn’t already been used (using an already installed Instance id will give error message from the installer).
Add this to the command line if you want CET to be launched after installation completed.
