Port 9790 in use - can't install MinimServer

I updated DSM to latest version (Above) and then Java to 8u71.

I then uninstalled MinimServer 0.8.3.1 (armV5) and went to install 0.8.3.4 (armV5) but got an error that Java wasn't installed properly. The Java install had displayed a message at the end saying that it had installed successfully but checking the log showed problems (patters then fixed the 8u71 download and I installed it successfully and it is running fine).

I then retried installing MinimServer 0.8.3.4 (and also retried 0.8.3.1) but get a message saying that Port 9790 is in use.

I have rebooted the NAS and the laptop a couple of times each and retried but get the same error.

Nothing else on the NAS or laptop has changed. The MinimServer installation instructions just say that this issue should disappear after a couple of minutes, but it doesn't.

I searched the forum but couldn't find a fix.

Can anyone help?

For future reference, you should not uninstall MinimServer before installing a later version of MinimServer or Java. You should just install the later version and it will automatically update your current installation.

It seems that the problem with the failed Java installation has caused the MinimServer installation script to malfunction. I will look into this.

To recover from the problem, you need to follow the instructions in this post.
