Error during installation

If an error occurs during PADS4 installation, a pop-up window appears with a “click HERE” link to the generated log file. This log records every step of the process, aiding in problem diagnosis. Share it with support if issues persist.
Never install PADS4 Foundation on a workstation or Viewer PC intended only for client apps like Designer, Scheduler, or Messenger. Doing so adds server functionality, reconfiguring it as a server machine and potentially disrupting client operations. After Foundation installation, you can add PADS4 client software on that server-classified PC.
