License Errors

When starting a MATLAB worker, a licensing pro blem might re sult in the

message

License checkout failed. No such F EATU RE exists.

License Manager Error -5

There are many reasons why you might receive this error:

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

which you are not licensed. Look at your

license.dat file lo cated 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 file. To avoid this, ensure that

each line begins with either

#, SERVER, DAEMO N,orINCREMENT.

After fixing your

license.dat file, restart your license manager and

MATLAB should work properly.

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

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