Thanks @David 

Also @Jason.Guan - it could be that your lens file was using a Project Directory instead of deferring to the general Zemax\Glasscat folder. Project Directories are new to 21.3 and provide a new lensfile-specific location for your glass catalogs. If your file is using the Project Directory option, but does not have the appropriate information stored in your project-specific Glasscat folder, then you will see a similar error. For more information on the new Project Directory featured, please see these links:

"Convert to Project Directory" new feature: two issues | Zemax Community

Hi Allie, 

       Thanks for the reply. From zemax setting I know the folder of glasscat, in my understanding that’s the folder where I should find all the material files. I think I am not using project directory feature since I haven’t chosen to convert to project directory. After reinstallation of zemax I saw material missing popup messages. I copied the glass file into the folder, then everything worked. It seems to me the new version just removed a few default catalogs.  

Hello Jason

I have checked on my side and it seems that AD5503 was not part of the default catalog. 

I will confirm this with my colleague in charge of the vendor data.
