unfortunately i was left short of the always important ssis input and output components on my ssis tool download. Yitzhak seems to be assisting a developer who was missing almost ALL of the components (i got most of them) but he seems to be directing them to the same download link i used. so i suspect my problem is somewhat different. his answer is posted at https://learn.microsoft.com/en-us/answers/questions/1341162/ssis-toolbox-missing-most-tools-that-should-be-ava and also shown in the image below.
