Some of the programs installed with ChemDraw Prime cannot be used.
With the release of version 18, we no longer have three different installers. There is one unique installer for all the licenses (ChemDraw Prime, Professional or ChemOffice). ChemDraw Prime does not include Chem3D, ChemFinder or ChemScript; so these programs will get installed but will not be activated. If you don’t want to have the additional applications installed, select Custom on the Setup Type during the installation. Once you click “Install” the second part of the installation wizard will be launched and you need to select “Custom Install” again to mark off the components that you don’t want. If you want to have access to these applications then you need to purchase a ChemDraw Professional or ChemOffice Professional license. If you install the software using the MSI installer, the MSIEXEC.EXE command line options can be used to remove the components that you don't want to install: ADDLOCAL=ALL, REMOVE=ChemDrawForExcel32 For example: msiexec.exe /i "\PerkinElmer\ChemOffice\PerkinElmer_ChemOffice_Suite_2019.msi" REBOOT=ReallySuppress ADDLOCAL=ALL, REMOVE=ChemDrawForExcel32 /qb Multiple features for exclusion can be listed as described here: https://msdn.microsoft.com/en-us/library/aa371194(v=vs.85).aspx "The value of the REMOVE property is a list of features delimited by commas that are to be removed." The list of available features for each of the installers are as follows: ChemOffice: Chem3D32 Chem3DActiveX32 ChemDraw32 ChemDrawActiveX32 ChemDrawForExcel32 ChemDrawQuickLook32 ChemFinder32 COEA32 ChemOffice 64-bit support: ChemDraw64 ChemDrawActiveX64 ChemDrawForExcel64 ChemDrawQuickLook64 COEA64 For Example: Like if you do not have to install ChemFinder and Chem3D from the installer, below should be the command. msiexec.exe /i "\PerkinElmer\ChemOffice\PerkinElmer_ChemOffice_Suite_2019.msi" REBOOT=ReallySuppress ADDLOCAL=ALL, REMOVE=Chem3D32,ChemFinder32 /qb"
