Hello, please post a screenshot of your GTA IV directory. 

Have you tried using the manual installer? Do you have a up to date version of the game? Please do the following:

• Make sure you aren't using a crack - We don't support cracks
• Update GTA IV to 1.0.7.0 (the latest version of the game, or 1.1.2.0 for EFLC) - This sometimes fixes a wide variety of issues
• Make sure that you run the game as an administrator.
• Make sure that your GTA IV root folder (and every subdirectory) is not set to "read-only"
• Ensure that ScriptHook.dll, ScriptHookDotNet.asi and Dsound.dll OR Xlive.dll are in the GTA IV ROOT folder
• Ensure that there is a folder titled 'LCPDFR' in the ROOT GTA IV folder.
• Check that all the above files exist, if they do not, reinstall LCPDFR with the MANUAL installation.
• Ensure that you are using up to date versions of every LCPDFR dependency and LCPDFR itself.
• Install these: .Net Framework 4.5, Microsoft Visual C++ Redist 2012

• Make sure you aren't using a crack - We don't support cracks: I have the 100% legal version, it worked with 0.95
• Update GTA IV to 1.0.7.0 (the latest version of the game, or 1.1.2.0 for EFLC) - This sometimes fixes a wide variety of issues: I updated it
• Make sure that you run the game as an administrator.: Did it
• Make sure that your GTA IV root folder (and every subdirectory) is not set to "read-only": Still nothing
• Ensure that ScriptHook.dll, ScriptHookDotNet.asi and Dsound.dll OR Xlive.dll are in the GTA IV ROOT folder: They are as in the picture
• Ensure that there is a folder titled 'LCPDFR' in the ROOT GTA IV folder.: They are as in the picture
• Check that all the above files exist, if they do not, reinstall LCPDFR with the MANUAL installation.: I have alway use the manual installation
• Ensure that you are using up to date versions of every LCPDFR dependency and LCPDFR itself.: I think I am, how do I cheack?
• Install these: .Net Framework 4.5, Microsoft Visual C++ Redist 2012: I have the C++ but remember about .Net Framework 4.5? I have the 4.0 is that ok or if not, can you help me resolve the problem from last time because I still can't get it working.

Green: Done already/not a problem

Yellow: Trying

Red: Failed

No, you need 4.5. Make sure you have the latest Windows updates. 

4.5 Installer keep crashing, what do I do?

Could you try disabling UAC? http://windows.microsoft.com/en-us/windows/turn-user-account-control-on-off

What do you think of the color coded list? I will keep updating it.

I already know what's wrong, you need .Net Framework4.5. 

Could you try disabling UAC? http://windows.microsoft.com/en-us/windows/turn-user-account-control-on-off

The UAC was never on.

I will be a little belated in my replies now, since I am going AFK. Make sure to uninstall previous version of .NET and then install 4.5

Ok, when you come back, I got the error message here:

I uninstalled my .net framework 1.1 and still crash and got that message, now I have no .new framework.

Found the problem, windows update keep failing, cheack out my other theread: '?do=embed' frameborder='0' data-embedContent>>

Well, that's an issue you'll have to contact Microsoft about.

You could try running a commandprompt and type "sfc /scannow" and let it finish.
