Prior versions of Windows, including Windows 7 and Windows 8.1, have limited support when running on new processors and chipsets from manufacturers like Intel, AMD, NVidia, and Qualcomm. For more information, see the Microsoft Lifecycle FAQ.
ArcGIS 10.6 requires Microsoft Visual C++ 2017 Redistributable (x86). If the Visual C++ 2017 Redistributable is not already installed, running setup.exe will install it before setup.msi is launched. Setup.msi will not install if Microsoft Visual C++ 2017 Redistributable (x86) is not already installed.
- ArcGIS software is developed and certified to support file system pathnames with a maximum path length of 260 characters, as defined by MAX_PATH. With the Microsoft release of the Windows 10 Anniversary Update, version 1607, it is possible to extend the 260 character limit for New Technology File System (NTFS) paths. While this is an opt-in behavior of Windows 10 Anniversary Update, doing so can result in unexpected behavior in ArcGIS and is not supported or recommended.
