We received a TC-08 driver update to support Windows 7 (software and reference CD-ROM R.49 USB SDK located in TC08sdk_r10.1.0.17.zip). We had the driver installation integrated into our application install but the manual driver update instructions (listed in USBReadme.txt) that used to work in XP with the older drivers doesn't work with Windows 7.
After following the steps for manual install, when you plug in a TC-08 the driver setup fails with a "missing file" error. If you install your data logger software, the installation of a TC-08 works ok. Looks like your SDK instructions/Files needs an update.
Following are the instructions in the TC08sdk_r10.1.0.17.zip USBReadme .....
Before using the examples for USB devices, kernel
drivers must be installed. The simples way to install the kernel
drivers is to install PicoScope or PicoLog. Instructions on manually
installing these drivers is as follows:
1 - Copy picopp.inf to <winroot>\inf
2 - Copy picopp.sys to <winroot>\system32\drivers
3 - Plug the device in and follow the new hardware wizard.
