The advantage of this workaround is that the problem will be solved for future Zemax files as well.

Workaround 1- One workaround is to change the Preferences in Zemax to Save As ANSI rather than Unicode. please change your Zemax File Encoding to ANSI *** For these cases, beginning in OSLO 6.6.0, the following message will appear under the Command Line: *** OSLO cannot read Zemax Unicode files. One possible cause of this problem is that the Zemax file (.zmx) is in Unicode text file format, rather than ANSI text file format. Symptoms Zemax file fails to open in OSLO. Synopsis Problem importing Zemax files into OSLO Question I have selected File/Import Lens File/Zemax, selected a Zemax file, but it fails to open.
