Hello. Today I got a message that it's necessary to upgrade Parallels Tools. During the installation I got a message: "Error 1402.Could not open key: HKEY_LOCAL_MACHINE32\SOFWARE\Microsoft\Windows\CurrentVersion\policies\system. Verify that you have sufficient access to that key, or contact your support personnel.". I don't know what to do Any suggestions?
try uninstalling the parallels tools from within windows, reboot windows, and install the tools again.
Solved! I uninstall the latest security update from Microsoft, restart and reinstall Parallels Tools. Now everything is work.
