After uninstalling Tachyon server
Uninstalling leaves behind the following artifacts. Like other Windows installers, uninstalling will leave behind any files, folders and registry entries created after installation.
| Location | Artifacts | Recommendation |
|---|---|---|
| Installation folder | You may find web.config files if IIS settings were modified after the previous installation. | Delete or rename the installation folder. |
| Logs folder | Log files remain. | Delete or rename the logs folder. If it is not deleted, a new installation using the same logs folder will continue to use the old log files. |
| Registry | Encrypted license details remain in HKLM\SOFTWARE\1E\Tachyon\LicData | The Tachyon registry key can be deleted or left. It is overwritten by the next installation. |
| SQL Server | TachyonMaster and TachyonResponses databases, as well as any databases used by additional installed components (Catalog, SLA, ActiveEfficiency), will remain at their corresponding SQL instances. | The databases can be deleted. If not deleted, the Tachyon Server installer provides an option to drop old databases or use them. |
Uninstalling 1E Client for Windows
Manual uninstallation
1E Client can be uninstalled manually by using Windows Apps and Features (appwiz.cpl). A reboot is not normally required.
Disabling a feature or client module
Please refer to Reconfiguring 1E Client for examples of how to use the -reconfigure command-line to reconfigure the 1E Client.
Uninstallation using the Windows Installer
1E Client can be uninstalled automatically by using a Windows Installer command-line, where the {product code} is dependent on the version of the 1E Client. The example below also includes switches that prevents prompting and restarts, and creates a log file.
msiexec /x {BF6F5FA9-64C8-4B72-A6B6-14A582BF96B8} /qn /norestart /l*vx C:\Windows\temp\1EClient-uninstall.log
Tidy up after uninstallation
After uninstallation of 1E Client, the following is left behind. As with other Windows installers, uninstallation will leave behind any files, folders and registry entries that were created after installation.
| Location | Artifacts | Recommendation |
|---|---|---|
| Installation folder | None. | |
| Logs folder | Log files remain. Please refer to Log files for log file locations of 1E Client and its client modules. | The log files can be deleted or renamed. If not deleted, then a new installation that uses the same logs folder will continue to use the old log file. |
| Client\Persist folder remains. | Leave this folder which contains status information about current instructions. The Persist folder should be deleted only if you do not intend re-installing the 1E Client with Tachyon enabled, or when preparing OS images. | |
| Tachyon client registry | HKLM\SOFTWARE\1E\Client\Persist | This registry exists if the Tachyon client feature of the 1E Client is enabled. It is used to keep a record of hash values for its persistent storage files, which includes status information about current instructions. This registry key should be deleted only if you do not intend re-installing the 1E Client with Tachyon enabled, or when preparing OS images. |
| Nomad Cache | %ALLUSERSPROFILE%\1E\NomadBranch | The folder should be deleted only if you do not intend re-installing the 1E Client with Nomad enabled. Downloaded content is retained so that if Nomad client is re-enabled it will be scanned and re-registered, to make available for peer sharing with other Nomad clients. |
HKLM\SOFTWARE\1E\Common and HKLM\SOFTWARE\1E\NightWatchman are used by the 1E NightWatchman Agent, previously part of the 1E Agent.
Uninstalling 1E Client for non-Windows
macOS uninstallation
To uninstall the 1E Client from a macOS device invoke the uninstall.sh script from within a sudo bash script. uninstall.sh is available within the scripts directory of the Apple Disk Image (dmg) file of the macOS 1E client.
Alternatively, enter the following commands inside a sudo bash shell:
bash$ cd /Library bash$ pkgutil --only-files --files com.1e.pkg.1E.Client | tr '\n' '\0' | xargs -n 1 -0 rm bash$ pkgutil --forget com.1e.pkg.1E.Client
Linux uninstallation
The following command-line can be used to uninstall the 1E Client on Linux:
sudo rpm -e 1e.client
Uninstallation will leave behind files, folders and registry entries that were created after installation:
| Location | Artifacts | Recommendation |
|---|---|---|
| Installation folder | None. | |
| Logs folder | Log files remain. | The log files can be deleted or renamed. If not deleted, then a new installation that uses the same logs folder will continue to use the old log file. |
| Client\Persist folder remains. | You should keep the Persist folder, which contains status information about current instructions, only if you intend to re-install the 1E Client. |
Solaris uninstallation
The Solaris IPS packaging system does not support pre- and post-install actions, so the 1E Client must be disabled before uninstallation.
sudo svcadm disable 1e.client sudo pkg uninstall 1e.client
If you protected the 1E Client's persistent storage, as described in Solaris installation, but no longer need it, then you will also need to run this command:
sudo pkg uninstall 1e.client.persist
Even if you did not protect the 1E Client's persistent storage, when the 1E Client is uninstalled the IPS system saves the directory at /var/pkg/lost+found/etc/1E/1e.client/Persist-timestamp , so it can be restored if necessary.
