rouble Installing KEPServerEX – Installation Failed (Error 1638) & Config Issues

Hello Community,

I am facing multiple issues while trying to install and configure K

1. Installation Failure:

   • When I try to install after uninstalling, the installation fails with Error 1638: Another version of this product is already installed.

   • I tried uninstalling completely, but it seems some remnants are preventing reinstallation.

2. Password/User Issue:

   • I forgot the pas.

   • I tried looking in UserInfo5.xml and other configuration files, but the options to reset the password are missing or invalid.

   • Right-clicking on OPC UA Config in the taskbar shows errors related to XML or missing configuration.

3. Current Goal:

   • I want to completely uninstall and reinstall it fresh.

   • I also want to reset the password so I can access OPC UA configuration.

Has anyone faced similar issues? Could you please guide me on:

• How to fully remove k and all related files/registry entries.

• How to reset the password safely without losing configuration.

• Any tips to avoid Error 1638 during reinstall.

Thank you in advance for your help.
