During installation
Windows may show a security prompt the first time you install MotorTranslator.
MotorTranslator is signed by KawanSoft using Microsoft Azure Artifact Signing. Even with a valid signature and certificate, Microsoft Defender SmartScreen may still show a blue "Windows protected your PC" warning when an installer is new or not yet widely downloaded. This is a reputation warning, not a sign that the installer is unsigned.
Click "More info", check that the publisher is "KawanSoft", then click "Run anyway".
Do not continue if Windows shows an unknown publisher or a publisher other than KawanSoft.
Your antivirus may also examine the installer the first time you download or launch it. The first
translation can trigger another short scan because MotorTranslator uses the embedded
WordBridge.exe helper for Office document processing.
Need a license key?
You can activate MotorTranslator with either a 14-day trial license or a purchased perpetual license.
