Any ideas how to restore Trackpad in BootCamp Control Panel?

Hello Loner_T 🙂

Selecting the "About Boot Camp" menu item from the system tray diamond gives me Version 5.1 Apple 2006-2013

The only Control Panel tabs I see are"Startup Disk", "Remote" and "Power".

I'm on OS X 10.10.5, if that's relevant at all.

Thanks for looking at this issue.

Thanks for all this Loner T.

I already have the Boot Camp installer I used in the very first instance still on my flash drive. I opened BootCamp > BootCamp.xml and the version number on the 7th line of that file is exactly the same version as on Apple's "5" software link page, namely 5.1.5621

I ran "Repair" from the USB yesterday but it didn't help. However, I'll run BootCamp > Drivers > Apple > AppleMultiTouchTrackPadInstaller64.exe now and post the results here.

I'll have a bash at the SMC and NVRAM too and report back.

Thanks again.

I have run the Trackpad Driver Installer but at the end I got the dialog shown in the attached photo. I clicked on "This program installed correctly". However, then trying to access to Control Panel resulted in an identical sequence (with disk modification confirmation request and only the three tabs) to my original post.

I'm not sure I understand the reason for your last post ... I have had 64-bit Windows 7 installed since around April/May this year and have used it on an almost weekly basis since and the trackpad has been fine. If I did install any subsequent Windows 7 updates then it was months back. This issue only began on my Mid-2011 iMac 21.5" just before I made my first post in this thread and it happened after the booting into Windows for the first time in about three weeks when I got an invitation from Apple Software Update on Windows 7 to update my Bluetooth drivers, which I did. I assume that is the cause of the problem, but presumably, short of deleting the entire Windows partition and re-installing I will not be able to find out!

I am going to try the SMC reset next and see what happens with that.

I appreciate your help.

Thanks again for all your help.

I plan to update Windows to Windows 10 to help support some potential employment. Windows 10 isn't supported on my iMac but others on here seem to have got it going just fine. If I can't get it to work satisfactorily I will simply delete it and re-install my Windows 7 as I did originally.

I have saved all my documents created on my Windows partition so that I can drop them back if things go wrong.

However, as part of this I installed 154(!) Windows updates and then at the end (after 5 restarts!) reinstalled the BC drivers - using the only option, repair - and now my trackpad tab and another have returned and all is well. So, hopefully it will stay fixed. Time will tell.

Thank you so much for your assistance, it's really appreciated.
