So I finally figured out after much testing how to install it properly.

1. Uninstall all programs for linking, student TI nspire software can stay as it doesnt give any problems, for me atleast, uninstall for more chance of succession.
2. Reboot.
3. Install TiLP
4. go to device manager and go to libusb, your device not there go to 5, if it is go straight to 8. (Step 5-7 are not a must, but i recommend them.)
5.uninstall TI educational device or unknown device at the usb bus controllers
6. reboot
7. let it install the ti educational driver.
8. Go back to device manager. Click update drivers on the Ti educational device/unknown device.
9. Browse manually for drivers, and then let me pick from a list on my computer.
10. you see the educational driver and under there TI-84+ silver driver! Yes thats the one we need.
11. try to install it, it fails right? Reboot and before it is starting windows hit F8, and click on disable digital driver signing enforcement.
12. Redo step 8+9
13. Start TiLP, go to change device(shortcut CTRL+D).
14. select  TI84+ click on the magnifier to search, change port number to the port number it shows.
15. change time-out to 10 seconds(fill in 10000) if you get the error, device timeout, which you almost certainly will get as that is the problem we get at ti connect, unable to communicate.
16. viola you got it working

OMFG
ALLL THE TROUBLE I GONE TROUGH 2 days and the threads i bumped up omg.

ah well  why did nobody tell me

but the problem didnt lie in the driver it was the timeout that caused the problem

that didnt work i tried

Thanks for that detailed procedure, but as hinted in reply #1, it has been obsolete for more than a year

TILP II 1.16 and newer can be installed side by side with TI-Connect, TINCS and TINCLS, in such a way that both TI's software and TILP can be in a working state at a given point in time on a given computer (without having to uninstall the other one). Obviously, they cannot communicate simultaneously with a given calculator.

Really? I was using TILP 1.16 and I had to disable driver signing in order to access TI84+ SE Driver. Perhaps it's just WinXP 

And just to clarify on your quote, TI-Connect setup has no option to not install the driver, so it screws everything up. Is there any way to disable that or will TI-Connect always have to be installed first for parallel to work?

I don't know enough to know what's going on or what's not working.  I have a TI-84+ (no idea if it's silver edition or not), and I can't get TiLP to connect to it.

Laptop is Windows 7 64 bit Pro
I had the TI software on there first, but uninstalled it when i found out that it wouldn't do what I wanted (suck a ROM out of my calculator).

Right now the calculator shows up as Other Devices, TI-84 Plus in Device manager.  I've tried searching the TiLP and GTK folders for drivers and neither windows nor I can find them.

I've uninstalled and reinstalled several times, no change.

When TiLP starts up, it does not see the calculator, nor does the "ready?" seem ready (ironic eh?).

All the documentation refers to things that I can't find explanations on.  I have a regular USB mini cable since the calculator has a builtin USB port.

This guide seems comprehensive, but I can't make it work.

How can I suck a ROM image out of my calculator on Windows 7 64 bit?

"Other devices" reads like it's not the appropriate driver (which would be under "Libusb-win32 devices"), and then, it's natural if TILP cannot see your calculator
Did you plug the calculator to the computer before installing TI-Connect or TILP ? In that situation, Windows installs its own, wrong driver for the device (neither TI-Connect, nor TILP can do anything with it), and then, you need to manually change the driver to TILP's driver (libusb0.dll/.sys, or the .inf file in Program Files (x86)\{Common Files}\LPG Shared\drivers\usb).
It's important to know whether your 84+ is a regular one or a Silver Edition: those have different USB PIDs. Silver Edition calcs have part of the top side (where you plug cables) near-white.
