Hello,
I am sorry about he issue.
Could you please check the situation after a clean reinstall of the software with these steps?

1) Uninstall the software normally, from the Windows panel.
2) Go to the path C:\Users\YourUserName\AppData\Local\Incomedia and delete the folder corresponding to your version of the software (it should be WebSite X5 – Evo).
3) Go to the path C:\Program Files and delete the folder corresponding to your version of the software (it should be WebSite X5 – Pro)
4) Restart the PC.
5) With the antivirus and firewall temporarily disabled, run as admin the installer you can find here: https://www.websitex5.com/download/v2024.4/wsx5_ev.exe

I remain available.

Eric
