License Errors

When starting a MATLAB worker, a licensing problem might result in the

message

License checkout failed. No such FEATURE exists.

License Manager Error -5

There are many reasons why you might receive this error:

• This message usually indicates that you are trying to use a product for

which you are not licensed. Look at your license.dat Þle located within

your MATLAB installation to see if you are licensed to use this product.

• If you are licensed for this product, this error may be the result of having

extra carriage returns or tabs in your license Þle. To avoid this, ensure that

each line begins with either #, SERVER, DAEMON, or INCREMENT.

After Þxing your license.dat Þle, restart your license manager and

MATLAB should work properly.

• This error may also be the result of an incorrect system date. If your system

date is before the date that your license was made, you will get this error.
