Browser blocking the EXE download? Some browsers and antivirus tools flag unsigned installers as suspicious by default. Use the ZIP variant instead:
After downloading, right-click → "Extract All…", then start
wposetupen.exe from the extracted folder.
When clicking the link you can choose "Run" or "Open" — the installer will start right after the download. WP-OPT© will then be installed on your computer.
If you choose "Save", the installer wposetupen.exe will be
placed in your Downloads folder.
Run the file and follow the installation steps. If a system reboot is
required at the end, please reboot before launching the WP-OPT demo
for the first time.
After successful installation you will find a "WP-OPT (demo version)" shortcut on your desktop. Double-click it to launch the demo program (or via "Start / Programs / WP-OPT (demo version)").
Older Windows versions are no longer officially tested but the demo usually still installs there.
WP-OPT© is available as a full version for professional use and an express version for educational or private use. For details and ordering, contact us:
