Windows Permission Stops and prevents uninstalling fonts

does any one have this problem?

I have finally gotten serious about my fonts and am organizing my fonts in collections and uninstalling a bunch.

I am using windows 10 creators and whenever I choose to uninstall a font I get the windows popup that makes sure I want to do this (aggravating when you want to uninstall over 400 fonts) - but after uninstalling 10-30 fonts that window seems to want to popup but it flashes away in a millisecond and now I do not have the option to uninstall a font until a reboot of the whole system  -- just closing and reopening CFM does not do the trick.

after I reboot the next time I will see if running it as the administrator helps-- if I can.  right now if I try to run CFM 2017 as administrator I get an error message.

any suggestions?

thx in advance, - handsome john
