I run Speccy 1.20.446 portable (fresh update with no INI file) on Windows 7 x64.
It starts and begins to analyze... everything and everywhere.
The problem is that this process never ends. And once I even received interesting message: "Cannot initialise SPC dll" (see e.g. http://forum.pirifor...showtopic=36971, http://forum.pirifor...showtopic=31732 etc) in couple of categories.
Then I shut the window (or click File -> Exit) - there is no problem - but... the process is still running and I have to kill it with Task Manager...
PS: long ago I used another version of Speccy on my machine and had no problems like that.
