I bought a license for version 5, but I’m unable to uninstall version 4.
I have windows 10 pro, and tried in safe mode.
It appears this message box “error: 3010”.
sorry for the trouble.
Please try the removal tool located at http://redeuro1.lulusoft.com/pub/pdfarchitect5/offline/Architect_5_Offline_Activation_22.214.171.124216.exe
