Back in 2009,
Zemax was using ANSI encoding for the ZMX files. In 2010, they switched from ANSI to Unicode encoding. This means that if you try to open a newer Unicode encoded file in an older version of Zemax, it will not load. The way to get around this is just to convert the file from Unicode to ANSI. I've done this successfully using a text editor, but they also added the ZPL keyword CONVERTFILEFORMAT to convert text files between ANSI and Unicode encoding formats. I haven't used it, but I imagine you could just run a loop on all of your ZMX files with this keyword.

文件，用高级些文本编辑工具打开后，另存为ANSI编码格式。之后就可以用旧版的ZEMAX程序打开，无需特殊的转换工具。
