UPDATE 8/3/15: With the release of Windows 10, Microsoft has once again moved the location of the Wintab driver. It is now found within a collection of other Surface drivers and utilities here.
You won't need to download the entire set. Just click download, then scroll down the list of available downloads and select Wintab-22.214.171.124-64-bit.zip .
Reader Dawn Griffin recently bought herself a shiny new Surface Pro 3. But when she tried to download the N-Trig Wintab driver to enable pen pressure in her Adobe CS 5.5 software, she was greeted by a rude error message.
Although the N-Trig site has been flaky before, this error appears to be different. Microsoft recently completed the purchase of the Israeli company's digital pen technology featured in the Surface Pro 3 and the Surface 3. The blog post announcement here is unclear whether N-Trig, Ltd. would continue as a separate company.
Judging by the disappearance of its website, it appears that N-Trig is no longer a consumer-facing operation.
When Griffin alerted me that the site and Wintab link were gone, I reached out to Surface Brand Marketer and Community Evangelist Markus Weickenmeier, who scrambled to find a new home for the Wintab download.
According to Weickenmeier, the Wintab driver will be available in the Microsoft download center from now on. "The URL will change with each update, but searching for Wintab will always get you to the latest version." Look for further information soon on the Surface blog.
As more and more software adopts Microsoft's RealTimeStylus model for pen pressure sensitivity, you may never need to install this legacy driver. But if you use older applications, it's comforting to know that Wintab support is still available.
And even if you don't install it, you may want to download it now and put it away for safe keeping. http://download.microsoft.com/download/2/0/7/2073C22F-2F31-4F4A-8059-E54C91C564A9/Wintab-126.96.36.199-64-bit.zip
