I've installed the BFG Manager on my new Windows 10 pc but it won't open from the desktop icon. Any help would be appreciated.

It's supposed to work in Windows 10.
First off, see if rebooting the computer helps at all.
See if using compatibility mode helps at all.

If that doesn't work, try uninstalling and reinstalling.
Make sure there's no antivirus blocking part of the installation, or keeping the client from opening.
I've never had trouble with Microsoft's Security Essentials or Defender, but some other antivirus may block things they shouldn't.

Also make sure you only get the Game Manager from Big Fish. Their link seems to be ***here*** but you can also go to http://www.bigfishgames.com/ click the link for "Help" and do a search for Game Manager to find the link yourself. If you get the Game Manager from some other site, it might have unwanted "something added" that an antivirus might be blocking.

I should know better. Asked my tech savvy hubby for help. He turned the comouter off and back on. Voila! Game Manager works. How embarrassing! Thanks for your help. Happy 4th.

All's well that ends well! Happy Fourth to you too.

Yes, it definitely works on Windows 10 - been using it for years. There is a saying in the computer tech world, that 99% of all problems can be solved with a reboot!
