Dell TouchPad (Alps) Windows 10 keep saying cannot delete file after startup

Dell Latitude E6430 upgraded to Windows 10 recently, all recent updates. Not sure when, after one of the driver updates, it gives an error at startup after login in:

File Access Denied

You'll need to provide administrator permission to delete this file

ApInfo.dll

Company: Alps Electric Co., Ltd.

If I press continue, it gives error that file is in use. Same error for all files in TouchPad driver. If I skip, touchpad works fine, the touchpad setting utilities work fine. But for some reason it wants to delete itself everytime system starts up.

Tried uninstalling the Dell TouchPad driver and reinstalling, several times, but always get the same error after login.

Any idea what could be the problem?
