I have both versions 3 and 4, plus any updates.

i have 3 computers. I never have more than 1 copy of youcam installed. However i have been trying to install on different machines, and then deleting the version on the old machine. Im doin this as im not sure which computer to use as my main one. If i could actually get your software to install correctly then id prob stick with that one. I also have 4 webcams, HD ones, logitech, creative, micosoft etc. Its the same trying all the cams. No noise reduction option is just not there!!!!
Soooo, basically ive done a lot of installing. Find out it hasnt installed correctly as the features you advertise aint there!
And lost count of the installs and then uninstalls.
It did work ok a couple of times some months back when i installed, i used to have the option of noise reduction which was great as my cam pic was very grainy.
But why has that option disappeared when uninstalling and then installing again on another computer?
Sometimes i also have sliders with the text missing showing what they are for ie brightness etc and some sliders never show up at all after installation.
The only reason i chose your software was due to the noise reduction feature.
Why does it vanish? i have purchased your software twice.
I have also tried the trial of version 5.0, again the noise reduction slider is totally missing.
