Error using ==> cd

I am using windows 7,64 bit. I try to run a simulink program.it gives me this error:

Error using ==> cd Cannot CD to C:\Users\...\AppData\Local\Temp;C:\Program Files\MATLAB\R2011a\simulink (Directory access failure).

my matlab program is installed at: C:\Program Files\MATLAB\ and I already checked this path in matlab. there is no thing wrong about it. I don't understand why matlab tries to find another directory!!! please guide me.

Are you trying to open a Simulink model file or just open the Simulink library? There might be some scripts linked to the model file through function callback. Did the error message indicate which line did the error happen? Can you copy the error message exactly (including line return) as it appears in the Command Window?

I am just trying to open a simulink file.

here is the warning in the command window:

Warning: Matching "From" for "Goto" 'Model_bus1/Fuel Cell/Goto4' not found

[Fangjun Jiang]

That's a completely different message. This warning indicates some "Goto" blocks are not needed because no matching "From" blocks are found. It's Okay. But previous message is an error. When did that error happen and did it cause any problem?

after running simulink program.the problem is that it can't find the right directory to run the program.

You seem to change the topic again. I am not sure what is your question.

here is the answer for your question.

Answer 1

[Walter Roberson]

Notice that it is displaying two directory paths with a semicolon between them. I do not know why, but it is trying to change directory to that entire path, semi-colon and all.

Does it give a traceback of the error? That might help us figure out what is happening.

to access matlab I have to connect to vpn. but matlab is installed in my computer. does it change any thing?

in the command window just there is this warning:

Warning: Matching "From" for "Goto" 'Model_bus1/Fuel Cell/Goto4' not found

[Walter Roberson]

The VPN to the license server should not change anything

[Ferd]

True, once license is established it will not change anything.

Make sure the file you are calling does not have a "space" in any of the files in the path. Try naming with underscores for spaces.

ı found this error's solution , is so simple. You just open the matlab as the adminastor. :))
