Current version of f-secure key not functioning properly on Windows 7.
Not a novice user. Have used Linux, FreeBSD, and VAX VMS.
Software engineer needs to modify code to make it function properly.
Sorry for my reply. I am only an F-Secure user (their home solutions).
Maybe it is useful to known more information about. Or even to contact their official Support channel (chat as example):
I tried to install F-Secure KEY 4.9.159 on Windows 7 64bit.
What is exact trouble with your experience? Does it autofill functionality? Or something else?
For example, I did not use some of previous F-Secure KEY builds and it is unknown for me about its design; but during my current try - I found that "system autofill" with some unclear points (delay before ability to get 'menu' and inability to fill exact string). But maybe it was overload with my system; All other things are valid for Windows 10 too - thus, good to know more about your situation!
