Hello I have been using a USB-AVRIsp programmer for years but two days ago I redid my system for a speed problem from 32 bits to 64 bits (win 7) and I can not install it anymore .
What I have done : I found on the net here and there according to the instructions of my training support. Instruction here:
> Installation for Windows 7 64Bit: > 1. Don't install any driver, and don't connect your AVR-Doper! > 2. Download the "avrcdc_inf.zip" from http://www.recursion.jp/avrcdc/l... > 3. Download DSEO from http://www.ngohq.com/home.php?pa... > 4. Unzip "avrcdc_inf.zip" > 5. Start dseo13b.exe, press "Next" and "Yes" > 6. Choose "Sign a System File" > 7. Type path from lowcdc.inf of the vista64 folder (for example: D:\avrcdc_inf\vista64\lowcdc.inf) and sign > 8. Choose "Sign a System File" again and sign lowcdc.sys > 9. Choose "Enable Test Mode" > 10. Restart System > 11. Connect the AVR-Doper, wait until Windows say that he can't find the driver. > 12. Open device manager > 13. rightclick the AVR-Doper, select update driver > 14. Choose the lowcdc.inf >
