Hi everyone,
I'm having the same issue with 4.52, also using Windows 7 x64
Also set the file association to "none", finding myself having IV associated to many file types.
Some of them, already associated with other programs seem to remain untouched (I have .bmp with Paint.net for example which avoids the 'hijack').
If I go to "Default Programs/Set Default Programs/Control Panel list" and look for IV, I see that many boxes are checkmarked but I can't uncheck any of them (I have administrator privileges). Using specialized tools (like Default Programs Editor) didn't help.
Haven't check using portable installation yet.
