Hello!
I suspect this is related to Windows Directx as it may not have completed install when it crashed.
It can be downloaded from here: https://www.microsoft.com/en-us/download/details.aspx?id=8109 . Note that Directx installer is a self-extracting file, so will not install automatically.
When you open the Directx_Jun2010_redist.exe file, it will ask for a location to extract them to. Type in C:\dx9 for the location, then open dxsetup.exe in that folder. (see attached screenshot). You can delete c:\dx9 when done.
Dear Don,
Thank you for your help. Windows 11 was reinstalled and Windows Directx was added. The ZEMAX-OpticStudio 16.5 SP1 was successfully installed.
Sincerely,
Mark
Dear all,
I have a problem about the Zemax 16 installtation on the win11.
When I first install the file 16.0.0 OpticStudio_Prerequisites,
it always crashes during the installation so that it cannot be installed completely.
I have updated the file Directx_Jun2010 already.
But it seems not useful for this case.
Although we can install the Zemax 16, it cannot show some analysis like spot diagram, MTF, as following
Could anyone meet this problem before and solve it already?
