How can I uninstall Foxit Reader from 16.04?

I installed it using the .deb package from their website and I've turned the internet upside down looking for a way to do so and nothing works, terminal doesn't recognize 'foxitreader' and when I use dpkg to list all the programs, it is just not listed, or listed below another name. HELP!

The installer tells you where the file was installed in. For me it was ~/opt/foxitsoftware/foxitreader. In that directory is "maintenancetool.sh", running it will give you a gui for uninstalling.

The foxit reader program is installed manually. To uninstall, go to ~/opt/foxitsoftware/foxitreader and then run ./maintenancetool file and click uninstall.

I was facing the same issue while uninstalling Foxit reader in my ubuntu 16.04. Then I did the following steps,

cd ~/opt/foxitsoftware/foxitreader/
sudo ./maintenancetool.sh

if I write ./maintanacetool.sh and try to uninstall, it was giving permission error so with sudo it worked fine.
