When the update notification balloon appears, I click restart and appear the message as shown. Why? (I have completed this first paragraph myself)
This is a coincidence, I want to share the experience of handling the error. A few minutes after I got the error message, then I restarted it but I ran it as administration via the path address C:\Program Files\Pingendo\Pingendo.exe(RUN AS ADMINISTRATION) and miraculously installed Pingendo version 4.1.12.
