If any system environment entry is extremely long, it may cause an error due to an internal buffer size within the SETUP.exe installation program (due to release testing on fresh installs of various versions of Windows, this was not caught for years). Typically the environment is modified by application installs, so a machine with many installed applications is more likely to run into this. Options include reviewing system environment settings, restarting the system, or run the installation process in a limited environment. This issue has been resolved for releases available after the first half of 2013. Note that 1.78 / pre-2010 releases will not be updated - options include running the MSI install, or modifying the environment to temporarily remove the entries that are extremely long. At a CMD prompt, you can use "set > env.txt" to create a text file (ENV.TXT) with the environment - view file size in Windows Explorer (the size should be under 700 bytes for SETUP.exe to run correctly). Typically there will be 1 or 2 extremely long items (path, etc.). You can modify the environment in Control Panel | System | Advanced Settings | Environment Variables. By saving the environment in a text file, you can safely delete items, then re-introduce them after completing the install.
