Hello! 

Yes, the normal behavior is to install new version in a new folder. There is no separate cleanup option.

The best thing at this point is to uninstall both versions and then reinstall the latest one which will ensure all file associations are correct. 

In future when upgrading, uninstall the previous version before installing the new one. That way you only have one version installed and it will work properly.

Thank you, Don. 

And zemax installation does not come with a uninstaller.exe. So, do I have to use the Windows → Add /Remove programs to uninstall the Ansys OpticStudio ?

Thanks

Greetings!

Yes, go to add /remove programs or Apps and features in the control panel. 

Hi @Don Dickinson,

A colleague has Ansys Zemax 1.02 and 1.03 installed on his machine, and when opening a file from windows explorer, the priority seems to be given to version 1.02. Even right clicking on the file, then selecting the 1.03 application from “open with” it will still open in 1.02. Is this normal?

Thanks

Hello!

I have never had anyone try to manually set the associations so not sure if this is normal. The OpticStudio version installed most recently becomes the default to open files so if you want to default to 1.03, uninstall 1.03 and reinstall it.

Hey Don,

May I make a suggestion?

The behavior of the installer hasn’t changed much from the days when ‘Zemax’ was delivered on two floppy disks in the mail, and specifying the installation directory was all you had to do. Given the size of the installer now, and how much more dependent it is on frameworks and the like it should maybe offer the option to remove previous installs. I know my hard drive is full of previous versions I did not intentionally archive.

I guess my point is, don’t feel the need to keep the installer defaults the same as when Ken first set it up.

I am having the same issue with versions 21.2 and 24. The only workaround seems to be to open v24 and then open my files from within the program.
