multisim10连好电路后开关打不开怎么办
无论怎么连电路,点开关就会出现"Error:C:\USERS\gqT=\APPDATA\LOCAL\TEMP\02.CIR:No such file or directory".另外还会出现对话框里面说“This circuit has no power sources:unable to determine the simulation timestep automatically.Please add a power sourse or set the simulation timestep under"Interactive Simulation Settings"to proceed.”但我明明安了电源,系统还原后重新安装还是有这个问题,请问这怎么办啊?
