That addin works on Eview 8 or higher.

Also, recent versions of Eviews have included ARCH method in their estimation settings.

You can also try STATA where you can explicitly selec DCC model.

I'm using Eviews 9. I'm not familiar with STATA but I trying to see if I can understand commands. 

Usually the problem because software , better you re-install eviews. 

It works better on stata 

Beside STATA, R is another option. R is free and has extensive packages including packages for DCCGARCH.

One example in Stata: wti and brent  are log returns of daily oilprices

mgarch dcc (wti = L(1/3).wti L(1/6).bren1 )(bren1 = L(1/3).wti L(1/6).bren1 ), arch(1/1) garch(1/1) vce(robust)
