You are using a very old version of SWV - the last one released before the product was end-of-lifed, was 7.6.269 which was Hotfix 10 in the 7.6 series. There should be a download link in a recent forum posting here.
Update: Got it working again, read my blog article http://how2appvirtualize.blogspot.no/2018/04/how-to-virtualize-oracle-java-8u161-in.html
