Hi, It’s looking more likely we have a new introduced issue.
If you have access to google analytics this shows it quite clearly: https://www.google.com/analytics/web/?hl=en#report/content-pages/a37926454w66427073p68310079/%3F_u.date00%3D20150601%26_u.date01%3D20150630%26explorer-table.plotKeys%3D%5B%5D%26_r.drilldown%3Danalytics.pagePath%3A%2Ftrack-installer.html%3Ffailure%3Dtrue%2526label%3DApache%20Flex%20SDK%204.14.1%2526version%3D4.14.1%2526os%3Dwindows%2526info%3DError%26explorer-graphOptions.selected%3Danalytics.nthDay/ Sadly the error tracking URL gives us little to go on: /track-installer.html?failure=true&label=Apache Flex SDK 4.14.1&version=4.14.1&os=windows&info=Error We’ve had 50 of these in the past 3 days and 0 in the past month. Most errors occur in non en_US locales (47 out of the 50) which may be an indication to where the issue may lie. This error is occurring at a higher rate than the "Unable to create temporary directory” windows error was previously. Justin
