Update not opening up

Hi everyone

i have updated to 8.1.6 and it just will not open?

If i click it again it gives the only one instance can run at once box pops up

any ideas?

Normally you get that message if you try to open the program twice.
So that “click again” was the cause of the message.
Just one click is enough, and have some patience if you don’t see any reaction immediately, the program might be busy starting up.
