What issue do you have?
I click on the Joplin application and the program does not open -I have tried the portable version and the desktop version
@AcomsDave welcome to the forum.
First check if you have a "J" icon in the system tray near the clock. It may be hidden behind an upwards pointing arrow. This would mean that Joplin has been set to run minimised (Tools > Options> Application > Start application minimised in the tray) and that Windows has not been told in its settings to always display the Joplin system tray icon.
If this is not the the solution:
If yes to all three:
I suggest this as in the past Joplin would actually open but it would, for some reason, display outside the bounds of the monitor screen. Admittedly I haven't seen reports of this happening for quite some time. Doing the above should reset it if that is the actual problem.
If Joplin has never ever started for you:
Just checking that you are not using Windows for ARM or a very old 32-bit system. I do not think that there is a Windows for ARM version and 32-bit has not been supported for quite some time.
