Plesk upgrade to 11.0.9 hangs. The last action that I see in C:\ParallelsInstaller\autoinstaller3.log is:
MSI: Execute cmd /c DEL /Q /F /S "C:\\Program Files (x86)\\Parallels\\Plesk\\PrivateTemp\\*"
System tries to delete all temporary files before upgrade. Wait when the action is completed or delete files from
C:\\Program Files (x86)\\Parallels\\Plesk\\PrivateTemp\\ manually.
A lot of temporary files in
C:\\Program Files (x86)\\Parallels\\Plesk\\PrivateTemp directory.
