Have.. an even simpler solution.
1. Look up OneAlex's GWX rework... as they do great conversion work... with GWX3 & this includes SH3Cmdr in it, as well. Simple download, unzip... drop where you want to (though,
NEVER in either of C:\ 's Program file folders... EVER.
) & after that... you're pretty golden.
2. Another GWX set to consider & pretty good, building on & furthering OneAlex's work.. is ToyotaGT86's work. As with OneAlex's, is straightforward fairly simple... d/l, unzip, install (making sure to note above in the 1 Alex notes) & you're pretty much golden.
3. Last, & most definitely NOT least, by any means... is Anvar1061's GWR (Grey Wolves Revisioned) work. This 1, does take a wee bit of making sure of how you install, (initially fer noobs & 1st timers... & maybe 2nd timers...
) but once you get used to it...
it generally becomes 2nd hat to ya... & afterwards, can roll through setting up... relatively pain free.
As with 1 & 2, (see notes on install...) set up where you desire for it to be.... & pretty much golden.
Hope this info helps... as always.
