Component Log FilesEnable 8dot3 Short File Names in the Installation Directory
By default, Windows 8.3 file name creation is enabled on each system drive. 8dot3 file naming generates short aliases for longer file names that contain spaces. For example, a short alias for “Program Files” is created as “Progra~1.” If, for some reason, short file names have been disabled on the directory where you install Analytics Server, errors can occur. In some cases errors are reported in the install log. In other cases, the installation appears successful but errors are reported for individual services.
To determine if errors are caused by missing 8dot3 short file names, follow these steps to verify whether or not 8dot3 file name creation is enabled:
1. Open a command line prompt.
2. Navigate to the Analytics Server installation directory.
3. Execute the following command: dir /x
If 8dot3 file name creation is enabled, the resulting output should list both long and short file names.
If the above procedure shows that 8dot3 file naming is disabled, use the
fsutil command to generate the necessary short file names. For information about specific errors related to 8dot3 file naming, and possible resolutions, see article
CS300197 entitled,
Windows Installer Error - "Error running cmd /c powershell...".
For additional information about 8dot3 file naming, see the Microsoft website article:
Fsutil 8dot3name.
