Cannot reinstall ultranav driver because of some DPInst.exe error.

2016-12-14, 22:37 PM

Hello all,

 

 

I decided to install a different version of the Ultranav driver on my ThinkPalled ad x220 laptop. I deinstalled the Ultranav driver using Programs and Feures, and then proceeded to install the Ultranav driver by running the executable I downloaded from thealla lenovo page at http://support.lenovo.com/nl/fi/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x220?c=1&beta=false.  The installation goes on fine up to the point when the driver has to be actually copied/installed, and then I get the error message "You have to run the 64-bit version of DPInst.exe on this machine. Contact the vendor that provided you this package."

What to do? The machine, as it is now, is nearly unusable, unless I use an external mouse. 

Solved! See the solution

I solved the problem: the installation executable I downloaded from the Lenovo website, created a folder, C:\drivers\win\unav, so I decided to update the mouse driver via System Manager, and when asked for the new driver, I just navigated to that folder. And now the system didn't complain! I just had to reboot and disable the touchpad - and now all is OK again!

What OS are you running? DPinst.exe is not supported on win 10.

Windows 7.

I'll never run Windows 10 on any of my personal computers.

WIN 10 rolls, hits rocks [i do have it].

What version of 7 and 32 bit or 64?

Please state the EXACT .exe name you downloaded from the support page.
