CVX installation error CVX_ version'' corresponding to input parameter of type 'char' is not defined

I don’t know why I encountered the following problems when installing CVX on my new computer:

run(‘C:\Users\JHQ\AppData\Local\Temp\Temp1_cvx-w64.zip\cvx\cvx_setup.m’)
UNEXPECTED ERROR: -------------------------
Function ‘CVX_ version’’ corresponding to input parameter of type ‘char’ is not defined.
error cvx_setup (第 20 行)
cvx_version( ‘-install’, varargin{:} );
error run (第 91 行)
evalin(‘caller’, strcat(script, ‘;’));

-------------------------------------------

Please report this error to support, and include entire output of
CVX_SETUP in your support request.

If using CVX 3.0beta, use CVX 2.2 instead.

If using CVX 2.2, I suggest filing a support request per http://cvxr.com/cvx/doc/support.html#bug-reports .

thanks a lot! i will try it
