Windows 7 64-bit Driver
When is there going to be a 64-bit driver available that is compatible with Windows 7 64-bit?
This version is
This version is fully compatible with Windows 7 64-bit. I just updated the text to reflect that.
I am running 64bit windows 7
I am running 64bit windows 7 and I am being told by LJ Self Upgrade that a newer version of UD driver is available. I have down loaded the latest 64bit driver but it is only version 3.15 while the 32bit driver is version 3.25. I don't need 64bit full fuctions so the 32bit driver is fine if I can install it. Can you please update the 64bit installer or provide data on how to install the newer 32bit driver.
Thanks
Mark
The new installer we are
The new installer we are using supports both 32-bit and 64-bit versions of Windows. Thus, if you use this link:
http://labjack.com/support/ud/ud-setup
It should update to the latest version. Note, you will need to uninstall the previous version before upgrading. We are working on changing the web pages to let people with 64-bit versions of Windows know they should use the above link.
