Found a fix, posting it for future searchers:open winecfg, go to Libraries tab, type "wininet" (without the parenthesis) in the box labeled 'New override for library' and hit the 'Okay' button. Look in the list of Existing overrides for wininet and be sure it says (native, builtin) after it on that line. If it does not click on the line and hit the 'Edit' button to change it. Apply changes, close winecfg, run program.
