Proxifier Standard Edition is distributed as a single ProxifierSetup.exe file containing all Proxifier files and the setup program. To install Proxifier on the target machine, please run this file as an administrator. Proxifier Portable Edition can simply be copied as a folder from a .zip package.
To install Proxifier silently (without user interactions), use the /SILENT or /VERYSILENT command line parameter for ProxifierSetup.exe. This mode is useful in unattended and remote deployment scenarios. The other parameters are available here.
Proxifier configuration can be deployed as a Proxifier profile file (*.ppx).
Users can copy predefined profiles to the following path on the target machine for the target user.
C:\Users\<username>\AppData\Roaming\Proxifier4\Profiles
On start-up after a fresh installation, Proxifier will load Default.ppx from this path. Files with other names will be available under Proxifier’s menu. To deploy a profile for all users on the machine, please put Default.ppx in Proxifier’s home directory or at
C:\ProgramData\Proxifier\
For more information, please see the Profiles topic.
Proxifier’s license key can be deployed using the following path of the system registry.
HKEY_CURRENT_USER\Software\Initex\Proxifier\License
You will need to add two string (REG_SZ) values:
Use the HKEY_LOCAL_MACHINE hive for system-wide registration.
Proxifier Standard Edition v4 uses a Windows Filtering Platform (WFP) callout driver to intercept network connections. This is the essential part of Proxifier. Only an administrator can install, uninstall, start, or stop the driver. All other Proxifier files, including Proxifier.exe, can be copied and run from arbitrary locations.
Normally, the driver is installed during Proxifier installation by the setup program (ProxifierSetup.exe), and it is located in the Driver folder of the target installation folder (usually C:\Program Files (x86)\Proxifier\Driver). The driver can also be installed manually using the command of the context menu of ProxifierDrv.inf.
To start or stop the driver manually (e.g., for troubleshooting), use the following commands as administrator:
Proxifier’s driver is signed with a modern, SHA-2–based code sign certificate. Unfortunately, such signatures are not recognized by some old versions of Windows 7 64-bit. When this happens, Proxifier cannot start and provides a Proxifier drive is not running error message.
Users may need an update to add SHA-2 support to Windows 7. Please follow this link to Microsoft’s site for more information.
