Hello folks,

if you can reproduce it, please specify exactly *when* does it crash ("clicked
X") and provide a debug trace
(https://wiki.winehq.org/FAQ#How_do_I_get_a_debug_trace.3F)

I have a notebook with DVD drive and tricked the firmware updater to ignore the
model until it asks if the firmware should be really flashed.

--- snip ---
$ winedbg --gdb ./GH22NS30_2.00.exe -q <<< "b *0x004081da"$'\n'cont$'\n'"set
\$ps=\$ps&~0x40"$'\n'cont$'\n'
--- snip ---

Gdb proxy mode ftw. Have a conditional branch go to desired location (clearing
ZF). Patching the opcode would work too, just to show alternative solution.

NOTE: it still needs a removable drive present to have this nifty hack to work.

Your description make it sound it crashes without any interaction at all which
I can't confirm. Even with old Wine 1.8 I still get asked "Do your want to
start F/W reflash?"
