Abstract: This article analyzes the common error 'A Setup Package is either missing or damaged' during Visual Studio 2015 installation on Windows 10. Based on official explanations, it details the cause—a server-side cleanup error—and provides solutions, including the fixed web installer and alternative methods like offline installation.
Introduction
During the installation of Visual Studio 2015 Community on Windows 10, users may encounter the error message: "A Setup Package is either missing or damaged." This issue was particularly prevalent during a specific period in September 2015.
Error Analysis
According to EricKn, Visual Studio Engineering Manager, the error was caused by an aggressive cleanup script on Microsoft's servers that inadvertently deleted the vcredist_x86.exe package, which is essential for the installation. This occurred from mid-afternoon PST on September 4th to 11:30am PST on September 8th, 2015.
Solutions
The primary solution is that the issue has been fixed on Microsoft's end, and the web installer should now work correctly. However, if users still face problems, alternative methods include using the offline installer (ISO image) or manually downloading and specifying the required packages, such as vcredist_x86.exe and vcredist_x64.exe.
Additional Insights
Other user experiences highlight the instability of the VS2015 installer during that time. Methods like repeatedly clicking "download from internet" or rebooting the system were reported as temporary workarounds.
