Erorr when updating to 2021 R6

[Frido]

Hello!
I tried to update to 2021 R6 an got the error "An error occurred while trying to replace the existing file: DeleteFile failed; code 5." See screenshot.
Is it fine to ignore and skip?

Thanks,
Frido

Hi Frido,

normally, a window opens informing about running instances that have to be closed before an installation. It might be that a "dead" process is still running but the GUI crashed. This might explain why our usual warning does not show.

A restart of your computer should end such processes, did you already try a reboot?

If this is not working, delete the folder C:\Program Files (x86)\Valentin EnergieSoftware\PVSOL premium 2021\ manually before installing.

Best regards,
Frederik

A reboot did the trick. Thanks!
