Today I tried to install the Adobe Flash Plugin for Microsoft's Internet Explorer. The basic idea was to download the executable, run it and have Flash installed. The problem was that somehow the whole process got corrupted which had several consequences. The Flash Player installation running in the background was creating new temporary Flash executables in the temporary cache directory. When I tried to terminate the process via Windows Task Manager I received the message that access was denied. This happened with the online installer. I received the message "Unable to Terminate Process The operation could not be completed The operation is not valid for this process".
I'm not sure what caused the issue, but what I did know was that I had to stop the installer from creating new Flash installer instances on my computer. With Windows Task Manager out of the picture, I had to find a way to terminate the process.
One of the best Windows Task Manager alternatives is Process Explorer from Sysinternals (which have been part of Microsoft for the past years). You can download the latest version of Process Explorer from here.
I started the process manager with standard rights first only to find out that I could not use it this way to terminate the process. After exiting and restarting it with elevated rights (by right-clicking and selecting run as administrator) I was able to terminate the process on the system.
I have learned two things this morning: First, that Windows Task Manager is not almighty when it comes to terminating processes on Windows, and second that it is definitely better to download and install Adobe Flash Player offline installers.
Did you ever encounter a process that you could not kill? What did you do to resolve it?
