Disclaimer : there is no guarantee that any of those suggestions will work for you, anyway, it doesn't cost anything to try them.
I'm just indexing here what (seems to) work for me and for other people. Hope it'll help some of you as well.
Yes, some issues are PEBCAK or "incompetence" fault, but some of them are not. Don't PM me for support request, use this thread.
Don't post here to be arrogant and saying "ELS doesn't crash, you're just a noob". ELS7 is wonderful and stable, but nothing is perfect.
Feel free to submit suggestions or ask support here. Maybe it's better than having hundred of similar topics about "ELS crashes".
This list will probably be updated when needed, in case of new fixes, new errors, and other suggestions/reports.
 
 

 

* FIX CENTER *

 

 
 
1) What to do first
 
A - Read, entirely, the awesome ELS User Guide (PDF) provided in the ELS7 archive. A lot of answers are already featured in this documentation.
B - Have a look at the excellent >Setup Guide by NicolaiB, the >Announcement topic, check tutorials, and also check other topics, maybe you'll find an answer here.
C - Be sure that all the ELS7 files are installed correctly, that you have the required components, and that there are not weird things in the ini files of ELS7 (almost keybindings).
 
D - Try to install default ELS7 on a fresh & clean GTA IV installation, launching a new game (no saved game), without any other mods except one ELS7 car of course.
Some savegames can be corrupted, some files can be f*cked up, and some mods can conflict (maybe like StrobesMod and his AI settings, but I'm not sure as I don't use it with ELS).
 
 
 
2) If you still have issues

 

Especially parts 2C & 2E, they are the most probable solution.
 
A - You can try Xliveless instead of Dsound (asi loaders), it worked for a few people, not me though.
 
B - Try removing "extra" parts from the vehicles.ide file, it seems to worked for me about ingame crashes after XX minutes of gameplay, however I'm not 100% sure.

Example for Noose cruiser :
Default noose line in vehicles.ide

noose,        noose,        car,        NOOSE,        NOOSE,        VEH@STD,    VEH@STD_RI3,        100,    999,        0.2345, 0.2345,        0.3,    2,    1.0    ,1,    ext_requi+ext_strong

Modified noose line in vehicles.ide

noose,        noose,        car,        NOOSE,        NOOSE,        VEH@STD,    VEH@STD_RI3,        100,    999,        0.2345, 0.2345,        0.3,    2,    1.0    ,1,    -

or if you need multiple liveries

noose,        noose,        car,        NOOSE,        NOOSE,        VEH@STD,    VEH@STD_RI3,        100,    999,        0.2345, 0.2345,        0.3,    2,    1.0    ,1,    livery

C - Try disabling ELS7 for AI cars in SinglePlayer mode. It's annoying, but, it works for 98% of people (it worked for me, but read "D" below).
In ELS.ini file, misc settings section, at line 55 : Ai_Els_Sp = off
 
D - If "C" above worked, check in the VCF files (in ELS folder) the AI settings for them. For me, the issue was "cruise lights" enabled for AI cars on bflo_vector.ini from LtCaine's ELS7 Modified Cars Pack.
I set it to "off" (OnForAiCars = off, at line 7), and in ELS.ini file I restored "Ai_Els_Sp" to "on", it seems that I don't have crash after loading screen anymore. So check attentively, it can be an individual AI setting as well.

 

E - If "C" above worked, you can also try to set the "ClearRandAiExtras" to "off" and re-enable "Ai_Els_Sp" to "on". If it works, then try to reduce a lot the "ClearAiExtrasDist" and re-enable ClearRandAiExtras.

If this last attempt doesn't work, then you'll have to disable ClearRandAiExtras. If it continues to crash, see "2) C" again. Majority of crashes are due to AI settings.

 

F - You can try to reduce some settings, ELS7 can be resource-intensive. Some settings that can help reduce lags and crashes (ELS.ini file) :

[ ENV LIGHTING ]
Range_PRML
Inten_PRML
Range_SECL
Inten_SECL
Range_WRNL
Inten_WRNL
EnvMult_Morning
EnvMult_Evening
EnvMult_Night

[ MISC SETTINGS ]
FlashDelay_Sp
FlashDelayWW_Sp
Els_Range_Pl
Els_Range_Ai
MaxElsCarsAtOnce
ClearRandAiExtras
ClearAiExtrasDist

Also, if your computer is a bit weak, don't forget to read the topics about improving and fixing graphics/resources issues.
 
 
 
3) Miscellaneous
Because some issues can be non-related to ELS7
 
A - As said at the beginning, try a new game, maybe you've saved a parked vehicle or you've saved as another ped than Niko/Johnny/Luis.
B - As said at the beginning, try a clean GTA install (or restore clean backups), maybe one of the recently modded file/vehicle screwed up everything.
 
 

 

What errors I had and what fixed those errors, if it can helps :
I didn't have any crashes at all since ELS7 release, but after installing LtCaine cars pack, problems appeared.
I had instant crashes after loading screen, solved by "2) D" tip above.

Part "2) E" solved crashes with another vehicles pack too. So, guys, try to disabling AI settings one by one, because AI ELS seems to cause a lot of issues.
I tested all the tips I've listed here, however I can't be sure about what works and what doesn't.
Even if I don't see any crash now, maybe I'll have one in 5 minutes ^^ so I can't tell I'm absolutely sure that my issues are solved right now, it needs longer testing.

Thanks cp702, I didn't dare to ask ^^

How do you get the environmental lights to show different colors for different cars? I am a bit confused on how to do it...? In the actual "ELS File" where the "default. config.ini" do I open it, set it up the way I want then save? Becuase when I do it just saves as a text doc not an ini and then doesn't do anything in game, so I'm a bit unsure how to set it as an "ini" which I'm assuming that is what it needs to be

 

Disregard, I'm an idiot.

I'm trying to edit the light patterns for each Lstg. Some of the light patterns for example [ SECL ]. Let's say the pattern I want for the [ SECL ] "PatId_Lstg1 =" is "E-20". 

 

Do I simply just put in E-20 or do I put E20 or what?

 

I'm sure I'm over thinking this lol. Appreciate all help :)

You just put the number.

Look at the User Guide provided by LtCaine.

 

PS : it's not the goal of this topic, we are here to solve common crash/perfs issues.

I've had some trouble messing with the light pattern, i hit the key to do the command but it wont do anything.

Read the UserGuide provided in ELS7 archive, read this guide '?do=embed' frameborder='0' data-embedContent>> too, and if you still don't understand what to do, open a topic with details and be as complete as possible.

This topic is here to help resolving major issues like crashes.

I used your guide to fix my game and it worked! but now it crashes when i press the key to activate the lights (j, or k or l) any thoughts would be great.

 

Thanks!

Need details about your cars, your config files, your computer, etc...

And try to use only one car with default ELS config (and maybe vanilla game) to see if it still crash.

I have a problem, all lights on my police cars are white? installing radiance didn't work for me though. Anyone else had this problem?

I'm running latest version of ELS, Scripthook. And EFLC Version is 1.1.2.0.

Specs:

Win 7 Ultimate 64-bit

8gb ram

GTX 560

i5 proccesor

Ummmm. I'm having some flashy light problems. It worked fine for a while. But now when I turn the lights on they all flash black. Like you can see the color of the light like red, blue , amber, etc. But when they flash it's black. And the reflection on the ground is red and blue which is fine I set like that. But I don't understand why it's black. Am I making sense ?

Sounds like a texture/model problem, not an ELS problem. Did you edit the model/textures?

No I don't know how to do that

Try reinstalling your mods
