I tried to install on my laptop. Got error message "Internal Power Error".
Googled, got a work around to try to disable all drivers and restart.
This was very difficult because computer locked up so quick I had to very fast to get to device manager to complete.
After many tries, accomplished.
Reboot I got the same problem.
Googled problem and found hits about driver conflicts with HP, Dell and Levno.
I reloaded Win 7 and all my software! Many hours, many updates!
How can I get compatiable drivers?
I checked I have a valid copy of Windows 7 according to MS./
Thanks for your help
