HomeTroubleshooting@RISK for Excel: Optimization (RISKOptimizer)"Subscript out of range" with Efficient Frontier Optimization

5.3. "Subscript out of range" with Efficient Frontier Optimization

Applies to: @RISK 7.5.0 only, Industrial Edition

I set up my optimization with Efficient Frontier, and clicked Start. Immediately I got the error message

Subbscript out of range

This is unfortunately a bug in @RISK 7.5.0. The error occurs only when (a) you are using Efficient Frontier (b) with constraints in addition to the special "Efficient Frontier" constraint, the one with multiple constraint boundaries, and (c) you have Simulation Settings » General » Multiple CPU Support set to either Enabled or Automatic. (The default is Automatic.)

The error has been fixed in release 7.5.1. If you still have @RISK 7.5.0, click Help » Check for Software Updates.
