Download

Choose the package that best fits your environment: installer or portable ZIP, available for both 32-bit and 64-bit Windows systems.

Which variant should I choose?

Setup (Standard): Recommended for most users. Installation creates shortcuts and makes future updates easier.
ZIP (Portable): Useful for USB sticks, test environments, or systems without installation rights. No classic installation required.
64-bit: Recommended for modern Windows systems.
32-bit: Only for older 32-bit Windows installations.
Beta: For users who want to test new features early. Not recommended for production or highly stability-sensitive environments.

If you are unsure, choose Setup 64-bit.

Warning Message from Windows When Running the Installer

PhonerLite is signed with a certificate from CAcert.org, a community-driven, non-profit certificate authority. Because its root certificate is not built into Windows by default, Windows SmartScreen may show the following message when you open the installer:

"Windows protected your PC" – "Unknown publisher"

This is not a sign of malware or an error—it simply means Windows does not recognize the certificate authority out of the box.

Standard Windows SmartScreen Bypass

If you see the standard warning prompt, you can proceed in two simple steps:

Click More info in the warning popup.
Click Run anyway to start the installer.

Optional: To permanently prevent standard SmartScreen warnings for CAcert-signed apps on your PC, you can manually import the CAcert.org root certificate into the Trusted Root Certification Authorities store in Windows.

Note on Windows 11 "Smart App Control"

If you have Smart App Control active on Windows 11 (Settings > Privacy & security > Windows Security > App & browser control), Windows strictly blocks applications that are not signed by a Microsoft-recognized commercial authority. In this mode, the Run anyway button is removed, and importing root certificates manually will not bypass the block.

If you encounter a Smart App Control block, choose one of these options:

Recommended: Use the portable ZIP version of PhonerLite. It does not require running an installer executable and typically bypasses setup blocks.
Disable Smart App Control: You can temporarily or permanently turn off Smart App Control in Windows Security settings to run the setup. Note: Depending on your Windows 11 build version, turning it back on later may require resetting your PC.
