[fpc-pascal] Fwd: Re: fcl-report demos not working on windows10/64 with win64 compiled - Font Arial not found

[Michael Van Canneyt]

Hello,

Can we please tackle one problem at a time ?

The first problem is: Why is the "liberation sans" not found ?

Once we've established that, we can check why the fallback is not found, and
perhaps the error message.

Michael.
