Bought BlueSoleil 8 a long time ago.
Then upgraded for free to BlueSoleil 10.0.417.0.
Updated my system to Windows 8.1 and BlueSoleil stopped working. Also, my system seemed to be slower than before.
I found out that the new version (10.0.472.2) is said to be compatible with Windows 8.1.
Uninstalled the old version (and my system returned to normal speed, so that it was!), installed the new one.
Cleared the activation record (not sure if I had to do that, 'coz the PC is unchanged, but I read somewhere on your site that's better to always clear the previous activation, before making a new one). First time I did that, an error occurred saying that there were no such a record. Second time did it correctly.
Activated the new version (the serial was already there, maybe because it hasn't been deleted by the uninstaller?).
Works like a charm!
Don't know why you guys have all those problems with installing :O
Just remember to clear your previous activation before activating again. If you've a BS8 serial it should work for BS10 too, just like in my case.
@rubbertail: if I manage to find my old BT keybd I'll make a try and see if your problem happens to me too ;)
