When I try to install tetra4D Converter I get the following message.

Setup has detected that Tetra4D Converter is currently running.
Please close all instances of it now, then click OK to continue, or Cancel to exit.

I have not installed yet how can it be running?


Thank you for your message. I have not heard of this issue occurring before, but sounds like there is the possibility of multiple instances running. My suggestion would be to completely uninstall all Tetra4D software, then perform a fresh installation. Also please be sure that you do not have two versions of Acrobat professional running.

If you continue to have issues, please create a support ticket by logging into your customer portal, or create a ticket from www.tetra4d.com/support and one of our technicians will be happy to assist.

Thank you for posting this in the forum and let us know if you have any further questions. Happy to help!
