Simulink error: Cannot CD to...(Name is nonexistent or not a directory)

Recently, I installed the MATLAB R2012b, but met a problem.

When I tried to open(there existed a button showing Open this Example) the model Simulation of a Bouncing Ball in the General Applications of the Simulink Examples, I even cannot open the model, the command lines showed that Cannot CD to C:\Users\123\AppData\Local\Temp (Name is nonexistent or not a directory). I did not know what happened, and what caused such things.

But when I opened the example Switching an Inductive Circuit Using a Breaker With no Snubber in the SimPowerSystems, the example can be opened, but when I tried to run the example, it didn't work, giving me a dialog box, showing Error in 'power_breaker/ 50V 60 Hz': Initialization commands cannot be evaluated. Caused by:Cannot CD to C:\Users\123\AppData\Local\Temp (Name is nonexistent or not a directory).

So here hoping to get a good result.

Having the same problem. Did you find any solution?

What is your system TEMP environment variable set to? Is it set to the path in the error message?

I think it maybe because your user in the Windows does not have a Administrator right. I met the same problem, and then I right click the shortcut of Matlab in my desktop and clicked "Run as Administrator", the error message is gone. I think you can have a try.

Right-click My Computer, and then click Properties. Click the Advanced tab. Click Environment Variables. Click the TMP variable, and then click Edit. Edit all instances of the TMP and TEMP environment variables so that they point to a valid folder to which you have access. Click OK, and then close all the open dialog boxes. Verify that the folder that you are using for the TMP and TEMP environment variables is accessible and has enough free space.

temp file in the C DIRECTORY of the path must be given full access control by right clicking the folder. and going to security and give full access, any of them will work

Dear Gnaneswar,

I had the same error. I changed the TMP and TEMP multiple times and then it workes for a while (day, some hours) after which it starts to give the same error again. I'm confused. Any solutions?

R2014a, Windows 8.1 64bit
