When trying to open Adobe PDF Reader today I received an error message "api-ms-win-crt-runtime-l1-1-0.dll is missing". Googled it and ran a repair through Win 7 Programs "repair" to no avail. Uninstalled and downloaded twice, same message. Then downloaded GIMP and had the same message. So, is this a WIN 7 issue or ?? I downloaded a free PDF reader and it works fine.
