Make sure that child folders are included in the exclusions. AntiVirus programs may have different options to do this unique to the program, such as using wildcards in the path (*), or an explicit option to add child folders.
Note: The paths above are based on a default installation of Tableau Desktop. If Tableau Desktop was installed in a non-default location, and/or the My Tableau Repository folder was redefined, please make sure that the exclusions match the corresponding paths of the non-default installation.
To help make sure these exclusions are set for full coverage and take effect:
Include the above paths and programs in exclusions for all scan settings, and if the AntiVirus has a list specifically for "Trusted Programs", add the .exe files there.
Reboot the affected machine.
Option 2:
Close Tableau Desktop.
Navigate to your My Tableau Repository and rename the Logs folder to Logs_Backup.
Re-open Tableau Desktop.
Option 3:
Close Tableau Desktop.
Change the Tableau Desktop Repository location from a network drive to the local disk on Tableau Desktop machine.
Re-open Tableau Desktop.
Cause
Anti-virus software is blocking Tableau processes from running, or the Logs folder contained corrupted information, or Tableau Desktop Repository location is not on local disk.
Additional Information
Check the C:\Users\<username>\Documents\My Tableau Repository\Logs folder to see if a "hyperd.log" file was created. If the file is not present, this indicates the anti-virus software may be blocking the startup of the hyper process, which is specific to Tableau Desktop 10.5 and higher.
