PhD2 on Mac fails to run - claims an instance already exists?

[Gary Spiers]

I've been using PhD for a long time and finally decided to try PhD2. Downloaded the latest version (v2.6.3) 5 minutes ago and when I try to run it I get the following error message:

"PHD2 instance 1 is already running. Use the -i INSTANCE_NUM command-line option to start a different instance."

Machine is a MacBook Pro running Sierra 10.12.4.

A look through running processes does not show PHD2 listed. tried deleting and reinstalling to no avail?

Thanks

Hi Gary,

This is a known bug (#485), sorry you ran into it. Luckily, there is an easy workaround -- you can just remove the file phd2.1 in your Home folder, then start phd2.

Hi Andy,

That works. 

Many thanks for the extremely prompt reply.
