So, no more ideas on how to make the mcp2200 driver installer behave while installing on Windows 7 with MUI language other than English (f.ex. Romanian) ? Specifically, in file: http://ww1.microchip.com/downloads/en/DeviceDoc /MCP2200%20Windows%20Driver%202013-02-21.zip There are 3 different mchpcdc.inf files and I assume there may be one more compressed inside the installer .exe . Should one install them manually by loading the .inf file or by using the driver update mechanism in Windows System Hardware or os there another way? -- Peter --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
