I'm currently running Plesk CP 9.3. I wanted to upgrade to Plesk CP 9.5.1 I shut down all services through Plesk System Tray Services Manager. I ran the Plesk 9.5 install it immediately said that it could not find a file. I rebooted. Plesk 9.3 loaded and was functioning. I ran the Plesk 9.5 install while Plesk 9.3 was running. The install program gathered data but came to the point where services were running and needed to be shut down. I went to Plesk System Tray Services Manager, stopped all services. Went back to 9.5 install, pressed Retry... I again said that Plesk Name Services was running. I went to task manager and shut down the PID#, it was Name.dll I believe, the Plesk Name Service. I again went back to install and it finally came back with 'error in \\pipe...\'. or something like that. Is anyone else having issues installing 9.5 overtop/upgrading 9.3? I've tried it many times and in different ways. It seems as if it wont even install unless Plesk CP is running, but the install keeps wanting me to shut down services. I'm going to give up trying to upgrade 9.3 to 9.5 and install on a seperate, fresh win2k8 server. I'd still would like to know what the issue is with the upgrade from 9.3 to 9.5. If anyone has any ideas or has had this happen to them please write.
