The current version of Xperia Companion (v. 220.127.116.11) had 2 errors on my PC (W7 64 SP1):
1) Setup with .DLL problem: I fixed the problem by installing an update for Windows - Windows KB 2533623 (Windows6.1-KB2533623-x64.msu) -, easily found on the Microsot website. After the update, the Companion was installed normally;
2) Several failures when trying to upgrade or repair my smartphone, such as "unexpected error", "login failure", "download failure", etc .: I corrected the problem by uninstalling the "Sony Mobile Update Engine", by Control panel. This software is installed automatically by the Xperia Companion setup. After uninstalling this software, Xperia Companion will no longer display any errors (and will install the Sony Mobile Update Engine again during the operation of your device, this time not causing the error!).
At least for me everything worked this way and, since I did not see this unusual solution on another site, I decided to post it, in case it would be useful to someone else.
