Possibly a silly idea, but maybe you can "cheat" by adding a .pdf suffix to the file name ... something like xxxxx.exe.pdf
Windows will probably try to complain, but you can tell it to go ahead anyway. Then try posting it.
Just be sure to caution everybody to strip off the .pdf suffix!

You specify the gear ratio and the plates you have. Enter the number of divisions you want and it outputs what you need.
In the Workshop Prsctice Series # 37 "Dividing"by Harold Hall are printed tables for 40:1, 60:1 and 90:1 gear ratios.
. In these table you will find the number of divisions, turns and hole spacing depending on the number of holes in the division circle.
Have a good day
