IronicTurtle:
Board- Arduino Uno R3
Software - 1.0.5
I recently got this: Arduino Starter Kit Multi-language — Arduino Official Store
Well I've never run windows 7, but I think that the latest IDE release 1.0.5r2 has new updated Uno drivers that are signed properly where I think the IDE 1.0.5 version had something wrong with the 'signed version'?
From the release notes:
ARDUINO 1.0.5-r2 - 2014.01.08
- Signed drivers for Windows 8.1
- Fixed Windows drivers signature (that prevented installation on
some Windows 8.x OS). Now the signature is timestamped and should
not expire.
Might be worth a try.
