Tak for din hjælp - ha' en fin (varm!) helg ! 
Hope you did not melt away. Fine the week-end was, but clocking above 32° in the shade behind the house sent us packing for the boat. Only to be fined by a police boat for not wearing life-jackets - going at 4 knots, 50 metres from the shore, wearing swimsuits ready to jump in. 22,8° water temp according to the police. The law really can be an ass sometimes... But to your issue. I just tidied up one of the family computers updating Win 10 to the April release. For some reason SH3D suddenly became unbearably slow and I had problems fixing DefaultUserPreferences.properties to display prices. Not to mention all sorts of other issues not related to SH3D.
In terms of SH3D I decided to scrap the current installation and use the portable version on the family computer. That worked much better.
Which made me think that - not knowing your project - you might consider using the portable version of SH3D (from the download page) on a USB stick or memory card.
That way you can let your clients use the USB-stick, pre-configured ready to use with different Operating Systems and with your own (priced) furniture library.
Just a thought. Keep us posted - and good luck.
ok
