So, Windows 10 has left you with a few programs that won't run? This is a modified letter we sent to a customer, it often does the trick. A customer has an older Detex ProxiPen system, that was not designed for Windows 10. We got the call December 27th, 2019 in the afternoon (Friday, Christmas week), and could not reach Detex. This solved it for him. If it does not work for you, then order the update disk, here: https://www.watchmanclocks.com/productdetails.aspx?ProductID=93
We'll have to try to fix it ourselves. Being a Detex dealer for nearly 20 years, we have a couple of ideas that may solve this:
Right click on the program app on your desktop. Select Properties. That will open up a box with 6 tabs. Security, Details,Previous Versions, General, Shortcut, and Compatibility. Select Compatibility.
In Compatibility Mode, use the drop down window to say Windows 8, then check the box above. Close the app, and relaunch it.
