I have been successfully using uVision V1.13 under Windows 95 for several years. However after recently upgrading (downgrading ?) to Windows ME I find that uVision reports the error "Unable to find Toolset" and fails to run. I have tried re-installing (several times) any ideas ?
Make sure that you have installed this software under 8.3 filename conventions. If you have installed it in the folder program files, this will not work in this fairly old release. Maybe you think about upgrading your software to Version 6. Version 6 solves all these problems.
