Windows 7 64 bit install of LO.2.2.2 on Dell 1370 Inspiron laptop. Hung on install - gots to about 10% and then sat there for an hour (until the battery went flat). Second attempt plugged in did the same.
Another report for this suggested ending wusa.exe would help. Found this, but it would not be stopped (I’d been waiting for 10 mins or more before looking). Stopped the installer (TrustedInstaller?), canceled etc the install etc…and then managed to end wusa.exe.
Restarted install - wusa.exe was not running - and as soon as it got to the 10% hang point, found wusa.exe had started, and immediately ended the process which it did this time, and the install continued without a problem.
