Hi, I cannot start simulator and ulink debugger after updating my toolset from version 2.50a to 3.00a . I reach a message telling me that sarm.dll is not found when I try to launch an application to debug. I controlled the path file and it's present in my install folder C:\Keil\Bin\sarm.dll. I think that the dll file is corrupted because substituting the file with the ones in version 2.50 simulator and debugger starts without errors. Please note that the exe downloaded from your site isn't corrupted (I downloaded it 2 times and from winzip's verify option it' allright)
