To install the Dyop tests, when you receive the file Release-V12.20.zip, download the file into your \Downloads folder.

Alternately, go to the file Release-V12.20  and download it.

 

Go to the \Release SUB-FOLDER in the \Release-V12.20 zip program folder and open the Dyop.exe file

to create a NEW (unzipped) \Release-V12.2 folder and \Release subfolder with the actual test.

 

Go to the UNZIPPED \Release-V12.20 folder and the \Release SUB-FOLDER and open the Dyop.exe file

which is the actual Dyop program.

Once you initially install and open the Dyop program, you need to copy and paste your issued License Key

in the startup panel to initialize using the Dyop tests. 

Press the F-10 key to go to the Setup Menu to calibrate the basic Dyop diameters per your monitor and the

patient viewing distance. 

Save those settings, close the setup menu, and proceed to enjoy the plethora of the Dyop test permutations.
