Warning this uses regedit and can mess up your system. Have someone else do it if you don't feel comfortable about editing
your registry. Smarter people than I may be able to cut out some steps and this process might be applied to other drivers. I
am not a computer expert! Well, this is how I got my Synaptics ps2 touchpad to work on my Benq. I hate Synaptics now and I
will never buy a computer that has a synaptics device again. The basic problem is that I believe since Windows XP service
pack 3 you MUST HAVE A SIGNED SET OF DRIVERS or it won't install and run on your system. Sure the programs installs it, but
windows won't recognize it! So you delete the driver and reboot. Humm, windows7 identifies a mouse, not a touch pad so it
installs the wrong driver- and guess what..its not signed and you are back to square one. What worked for me. Logon as a user
with administator rights. Step 1. Download and install the "Universal Extractor" from FileHippo
Download Universal Extractor 1.6.1 - FileHippo.com Step 2. Download but do not install the windows 7 version of the
synaptics driver.
Link Removed Step 3. Go to control panel-progams and feature and uninstall
anything synaptic Step 4. Reboot Step 5. Go to control panel-system-Device manager-View and check -Show hidden devices. If
something new shows up under mice and other pointing devices. Right click and delete the device/drivers. Step 6. Boot to safe
mode Step 7. Start regedit Step 8. Use the search to find synaptics check whole word option. Step 9. Search and delete
anything that shows up until the search doesn't find any more locations. Step 10. Reboot back to safe mode Step 11. Go to
control panel-system-Device manager-View and check -Show hidden devices. (Make sure you don't delete the HID mouse!) If
something new shows up under mice and other pointing devices. Right click and delete the device/drivers. Step 12. Find the
file you downloaded from synaptics, right click on it and look for the option - unextract to subdir. It will ask which mode
to use-pick- "not an install shield" and extract. Step 13. Open the new file directory-
Synaptics_v15_2_20_C_XP32_Vista32_Win7-32_Signed_Marketing_SGS94_UI-Scrybe and click to run dpinst.exe This will install the
SIGNED drivers you need without all the other **** from synaptics. Step 14. Reboot and go to the logon that gives you
administrator rights. Step 15. AGAIN-Go to control panel-system-Device manager-View and check -Show hidden devices. Something
new should show up under mice and other pointing devices- PS2 touch pad. Right click and read the device/drivers details, it
should say you need to reboot to activate the new drivers. Last Step- Reboot, unplugging the usb mouse you were no doubt
using, before windows starts and PRAY. Good Luck. Mine works now after 3 weeks of trying. I tried almost everything including
signing the old drivers using a 3rd party signing program. This is the only thing thats worked. Good Luck By the way, I used
to trust FileHippo downloads. Now several of their programs are installing **** that you don't want! Make sure you read the
agreement until the end or you will be signing away your bandwith to various advertisors in a very sneaky way. I have found
the "free" pdf programs to be especially dangerous.
