In windows, just installing the non-net over the older version works. In fact you can swap back and forth between them with fresh installs as the key file that changes is SierraChart.exe.

Not sure why it would be a problem with wine. If it was me I'd just uncompress the sc installer and take out the three files that change with most upgrades and substitute them in the wine directory (make sure that linux / wine doesn't have extra copies hidden around though).

Thanks Spidey. I'll have to look into it a bit further I think before knowing for certain.
