XnView Software

I'm not saying i don't like this software. On the contrary, i enjoy it. However, sometimes i need to re/uninstall it.
The problem is that i always use the install way of unzipping the downloaded achive file into a certain file. So when i want to re/uninstall it, there will be a error prompt telling that some kind of .dll file is under use.
So would you tell me how to uninstall XnView in my case, please?

The file in question is probably \XnView\ShellEx\XnViewShellExt.dll.

You need to untick the checkbox for Use XnView Shell Extension (Tools » Options... » System Integration » Integration).

thank you
but still hope to have a uninstaller
