  • Plesk 11.0 for Windows
  • Plesk 11.5 for Windows


An attempt to upgrade Plesk fails with the following error:

ERROR: Unexpected 'class boost::filesystem::filesystem_error' caught: boost::filesystem::rename: Access is denied: "C:\ParallelsInstaller\parallels\PANEL-WIN_12.0.18\examine_launcher.exe.tmp", "C:\ParallelsInstaller\parallels\PANEL-WIN_12.0.18\examine_launcher.exe"

The file is in "DELETE PENDING" status in Process Monitor utility


During the Plesk installation or upgrade "examine_launcher.exe" is downloaded twice to the same location. The second attempt fails because initially downloaded file cannot be replaced. It happens because the deleting of this file by system takes long time.


It is required to start "Application Experience" service under Start -> Administrative Tools -> Services and then start upgrade again.
