You might try the solution offered by a VMWare tech for this same problem with 8.5.x. First of all, uninstall Fusion and all of its components.I just upgraded to 10 and I'm getting this error whenever I start any VM? I tried uninstall/reinstall 10.1 same issue
Thanks
Then, after downloading the installer again, if you need to (substituting your path and 10.x version number in this Terminal command)
xattr -l ~/Downloads/VMware-Fusion-8.5.8-5824040.dmg
xattr -dr com.apple.quarantine ~/Downloads/VMware-Fusion-8.5.8-5824040.dmg
It worked for me.
