I'm new to lcpdfr and all the different mods it has to offer. I was wondering why none of the mods I download and put into my gta iv folder work? I follow all the instructions but none of the mods work. For example I downloaded an ALPR reader and whenever I press F5 it doesnt open up. Or with the trainer. I press F3 and nothing happens either. Same with the vdh police helper it doesnt work either.  I even downloaded the Scripthook v1.7.1.7 and that causes my lcpdfr to not work. I've searched all over to find the answer to these problems and I just can't seem to find an answer. Can anyone help me?

Have you read the readme for all those mods you've just listed?

Yes and none of them seem to work for me. 

That's really weird. If you follow the instructions to the letter it really should work. Could I see a screenshot of your GTA IV directory? 

Here is my directory. Also thank you for being willing to help me!

You are using both xlive and dsound, please remove one of them. 

I have removed dsound from my directory and I have tried adding the trainer into the directory yet I still cannot open it while in game. Am I doing something wrong?

UPDATE: I have gotten the trainer to work. All I had to do was hold down the Fn key then press F4 for the trainer to open up! 

 

I did the same and tried pressing F5 while holding down the Fn key for Bravehearts ALPR but I'm not sure why it won't open? I've installed both .ini and .dll files. Is there a possibly explanation to this?

Hm, are you using a laptop by any chance? 

Yes I actually am thats why I have to press Fn each time I want to open up the trainer haha

Yes, I thought as much. Laptops aren't ideal for gaming sadly :/

Alright this is my last and final update. Being the noob that I am, I didn't try adding the .ini. and .dll files to the "scripts" folder in the GTA IV directory until now. I've finally got all the mods working! 

Yes, that would solve the issue. Mods ending in .net.dll (as well as other extensions, .net is most common) and their .ini files go in the scripts folder. Mods ending in .asi and their .ini files go in the main directory.

Thanks for confirming that with me! I can finally use all the mods now and its great.
