hyperstudy: Error in Running several optimization with same model with Excel
Hello, once I have defined a model in Hyperstudy with Excel, It works well to do one optimization. But then, I want to run a new optimization, I always get this error that it cannot find the excel, and thus cannot run the optimization. And the Excel is there, so I dont understand. See images for more info. Thanks a lot!

新しい DOE に、既存の DOE の結果を追加する例題
始めに HyperStudy では、新しく作った DOE を実施する前に、すでに実施した DOE の結果を追加することができます。 これにより、重複する計算を省略することができたり、複数の DOE の結果を一つの表にまとめたりすることが用意になります。 なお、DOE を例として挙げていますが、最適化でも同じです。つまり、正確には、 「新しく作った DOE または最適化を実施する前に、すでに実施した DOE または最適化の結果を追加する」 となります。 例題 HyperStudy アーカイブファイルのダウンロード: https://us.v-cdn.net/6038102/uploads/LSIACWYAXLZP/study-1.hstx…
