How to uninstall a software?

Hi All,
Yesterday I installed a software in the Comodo Sandbox by selecting the EXE file and right clicking and then running it under Comodo Sandbox(via context menu). All went well and the program installed successfully in the sandbox and I tested the software.

I want to uninstall it now. But the problem is that it is not listed in ADD OR REMOVE PROGRAMS.

Please tell me how it uninstall it ?
Also please tell me why it is not listed in ADD OR REMOVE PROGRAMS.

Thanks

For sure it won’t be at Add/Remove programs…
If you run it sandboxed and virtualized, when the computer booted, the files/registry keys are gone.

But the installed applications folders are still in C:\VritualRoot. Also the registry keys are not gone after reporting ???
