I'm trying to install Composer 2017 and Composer 2017 player on the same PC, but in doing so I get and "Error 1312 Cannot create the directory C:\Program Files\SolidWorks Corp\viscg2glsl.dll. A file with this name already exists. Please rename or remove the file and click Retry. or click Cancel to exit.
I install both of them on the same machine all the time.
You can use a command like the following if you are installing from the manual installer or the admin image folder:
"MSIExec.exe /I "E:\Installers\SW2017SP5\64bit\SOLIDWORKS Composer\SolidWorks Composer.msi" INSTALLDIR="C:\Program Files\SolidWorks2017\SOLIDWORKS Composer\" ACTIVSERIALNUMBER="0000 1234 5678 9000 ABCD F43D" ACTIVSERIALNUMBERPLAYERPRO="0000 1234 5678 9000 ABCD F43D" ADDLOCAL=Licensing,Eula,InterOps,LicenseSupportFiles,PlugIns,SWComposerCommon,SWPlayer /qb"
If you are installing on a machine that already has composer installed on it you can use "REINSTALLMODE=vomus" before the /qb in the command.
