This comment saved my life! SurfacePro3 / i5 / 8g RAM / 256g hard drive running Windows 10 - we had a panel of touchscreen where touch was not being recognized. The link to the sony calibrate tool mentioned in Reddit forum (Link
to reddit forum) was not working. However the Reddit forum was extremely helpful since so many had experienced this issue and solved it.
So I manually found the driver on Sony website another way and downloaded it from here:
https://www.sony.com/electronics/support/svf-series-svf15n1-series/svf15n190x/downloads/W0009338
However, since that driver is made for Windows 8, I got the "msvcr100.dll" error like the poster mentioned above. When I downloaded the Visual C++ drivers for Win X64 and installed them, the CalibrateG4.exe tool worked like a charm and fixed our touch screen
issue. Thanks to all that helped post these!
