I recommend sticking to the WinXP SP2 OS and formated disks. (stay away from Win98 for now as
we dont have much to offer in helps on that OS).
Below are the steps I recommend you try explicitly (start from scratch):

1. Install LB2 and install the english or international patch (I recommend the e-patch for starters as its the most tested)

2. Install LB2 DDU patch, even if you intend to
use 3DFX and not D3D graphics engine. The out-of-the-box install uses the 3DFX graphics engine, so its "optional" to install this DDU patch if you intend to stick to 3DFX.
However, if you plan on running D3D its required.
Again, I recommend installing it anyways, as Ive had success running 3DFX on 3 systems doing this and I dont know how many others Ive helped getting LB2 going on various rigs.

3. Run the new utility deposited by the DDU patch called "lb2cfg.exe", and select 3DFX.

4. Edit your CA.INI file and put this at the top:
[Backdoors]
HEAP_PERCENT=0

5. Use the "System Configuration Utility Method" which edits your BOOT.INI file and limits your RAM to 366mb. The reason I recommend this is that it doesnt install anything and is pretty easy to get right. Remember to reboot after making the changes, and to unset it after your done using it.

6. Use a GLIDE wrapper.
The older video cards you have might not need a glide wrapper, but its probably essential to have the correct 3DFX drivers that were used back then. Heres one place you might try to get 3DFX wrappers for the older cards:

Below is feedback from a guy that ran a V5 with WinXP, which is closer to what youre doing:
----------
So, problem solved on XP PRO with Voodoo 5 card:

1) Don't install glide2.dll and glide3.dll.
2) Do not put them into the windows\system32 directory!
3) Do not REPLACE your current glide2.dll or glide3.dll!

Simply extract them to the main LB2 directory!
It seems that you MUST HAVE THESE glide2.dll AND glide3.dll FILES IN THE LONGBOW DIRECTORY
--------

So you might try without the dgVoodoo glide wrapper first. If that doesnt work, then try the wrapper.

I recommend the dgVoodoo 1.40+ version (there is newer, but little testing has been done with the 1.50). Get the dgVoodoo wrapper here:

Set it up like shown below (Glide tab settings):



Then kiss the monitor and give it a go...

thanks so much for you attention and help, iŽll try it tonight when i get home.

thank you all for your help, attention and caring, but i give up!
couldnt make this game run neither on xp or 98se....with exception of JF-18 all my old games runs fine in xp without me having to tweak anything, but this longbow just dont wanna give me his grace. maybe with my luck i got a corrupted cd, although its weird the problem only shows up when im about to start a mission, damn teaser beech.
is there a way to config the game externaly of the main game system? like il2,fb? cos even in game there is no such option, that would be my last ,if any, hope.
i should had no problem at all since the demo runs smooth here. both xp and 98.

(sighs) i definetely aint buying another copy...

well, if thats it, thanks again for all your caring, see you in other sims though.

You didnt get your CD from that MOMIME guy on Ebay did you?

Stay away from him like the plague.

So what did you do following my explicit directions,
and what didnt work.

You have to be our eyes.

i did every single thing you told me to do in the previous post with the exception of the instalation of LB2 DDU patch ,since it refused to isntall, but i doubt it would make any diference anyway. i even kissed the monitor but then he gave me a grin smile.....it was scary

Funnily enough, I'm having exactly the same problem trying to get LB2 running on my XP system.
I installed the program and it worked for one flight!!
Now when I start a mission is flashes the LONGBOW 2 screen up momentarily and then says that it has to close down and returns me to desktop!
How frustrating is this?!!!!
Arrrrrggh!!

at least yours worked once, thats a sign it may work again, mine stop in the very moment the game will start after loading all the crap from the mission.....

BLADERJ,
"No tongues" when kissing the monitor...
(from Young Frankenstien)

Seriously,
- what video card did you use?
- what video drivers and glide wrapper?
- what version of LB2 (English) and patch?
- and insights as to why DDU didnt install?
- did you try software mode?


DJF,
Running once is such a Brit thing. (joking)
Seriousy, tell us more about your system and
what you did when you follow the instructions above.


Success is usually a couple of steps beyond giving up.

lol, oh the American wit!! That's why we love you guys so much here in the UK! Ha ha.

I'll get back to you on what I'm running, it's a new system so I've not actually looked properly yet but I've done pretty much everything suggested here. Stand by, I'll be back with my setup.

OK, firstly, you'll have to bear with me, I'm not very good with computers so the jargon tends to baffle me!!
I'm running XP on a system with a Celeron 2.6 GHz processor with 192Mb RAM.

Can't find out what graphics card I have but I have a feeling that it is an integrated one.

Gone through those instructions again and I'm trying to find out how I can do step 5 (the system configuration utility method)? I don't have a clue!!

Please can somebody give me any clues??!!

Dan.
