Trial DLL still shows up after uninstall

Sometimes DLLs are not unregistered if the file is in use by some application.

Please follow this guide:

1. Reboot your PC to make sure DLL files are not locked by any application.
2. Run the file InstallAsActiveX.bat As Administrator. It is located in the following folder by default: c:\Program Files\Bytescout PDF Extractor SDK\ActiveX\InstallAsActiveX.bat
