Attached are two pcgen character outputsheet files, I use as the basis of my enworld character sheets. I know there are a few issues with spells but otherwise they should work.
Having installed pcgen, you need to copy theses files into the outputsheet/d20/fantasy/text directory. As I don't use windows, I can't tell you where exactly this is located but at a guess it should be under Program Files/pcgen.
Once installed, run pcgen and select Settings,Preferences. In the preference window select output and select the required sheet in "Default HTML Output Sheet". Once the new sheet is selected then every time you "Preview the current character sheet in a browser" it will create a new browser window using the selected sheet. Please note that these sheet are intended for use in ENWorld, which uses BBCode not HTML, so they will only look as intended when loaded on enworld. If you want to display your character sheet in a browser use one of the pcgen default sheets.
Hope this helps. Please let me know if you have any problems.
