I think I finally understand the problems.If your browser doesnt associate.zmx files with ZemaxOpticStudio, then it tries to do strange things with the file when you double-click it; my browser tries to play them as music files.
Zemax Download The FilesTo get around this problem, first download the files to your disk, then open them from Zemax or Windows Explorer.The second problem is trickier; older versions of ZemaxOpticStudio may have problems with files saved by newer versions. From what I can tell in the comments, these problems are limited to archive files (.zar.) Zemax has helpfully investigated the issue, and their Mark Nicholson reports, There should be no issue with opening a.ZMX file produced by the current version in any earlier version. Youll get a message popping up to say that the file was produced with a later version and so it may contain surfaces, operands, features etc that are not available to the older version, and so care should be taken. Thats all. ZARs are different. The ZAR is a compressed file that includes all the data files needed to open a ZMX, as well as the ZMX file. There have been occasional changes to the ZAR format that render ZARs from later versions unreadable by earlier versions. We certainly go to great lengths to ensure that any old file works 100 with any new version of Zemax software. We just cant future-proof a version so that it can always be guaranteed to open a later versions files satisfactorily. The files posted here contain nothing more fancy than Even Aspheres, so I dont understand why the files might be difficult to open. In case anyone is still finding problems with opening the.zmx files, there are still two workarounds. A less expensive workaround is to edit the.zmx file so that the first line refers to your version of Zemax. In Notepad, navigate to the folder where you downloaded the.zmx file 4. In Notepad, choose all files from the dropdown menu next to the filename box. Select the.zmx file youd like to edit 6. Zemax License Number ForSee that the first line of the file contains information for the version number, coded VERS YYMMDD NN LLLLLL where YYMMDD is the date of the version of Zemax that created the file, NN seems to be an index for the file number, and LLLLLL is the license number for the Zemax seat that saved the file. Change the YYMMDD to the version date for your Zemax, or earlier. Ive successfully opened files with the code 010101. Save the file with a.zmx extension by choosing save as, then typing the entire filename in the box, with quotation marks. Because of Windows defaults, saving as dan.zmx will save the file with the proper.zmx extension; but saving as dan.zmx will actually save the file as dan.zmx.txt, which may give Zemax difficulties.
