Help! I've been running ActivePerl for years now & have scores of scripts running to manipulate data & update websites. Last night Windows 10 did a major update to Build 1607 (the 'Anniversary Edition'). Perl no longer works! The cmd window opens but nothing happens. When clicking on a .pl file, I get a UAC warning about 'no publisher' and then the same dead cmd window. I tried installing Strawberry. That eliminated the UAC warning, but still won't run. I've had to fire up my Win 7 machine as backup. Has this happened to anyone else?
