I have been using the TC08 Serial in Windows XP and Labview 8.2. We recently upgraded our PC to Windows 7 64 bit and Labview 2013. We got the Labview runs on Windows 7 however the Pico reads 0 Degree Celsius, so I think our TC0832.DLL does not work on Windows 7 ?!?!? Does anybody know if the Pico TC08 Serial works with Windows 7? or it looks like we have to upgrade our TC08 serial to TC08 USB (which Pico said works with Windows 7)? Upgrading our TC08 serial would be a cost impact since we are using quite a lot those units. Please help.
