Error Message

Enterprise Vault attempts to discover which application is requesting the system restart and displays the following message:

"A restart from a previous installation of <application> is pending.
You must restart the computer to complete this previous installation
before you run the Enterprise Vault installation.
See the log for more information."

• In the installation log file, you may also see the following: 

ERROR: Pending reboot detected in registry key : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce

ERROR: Value : "C:\PROGRA~2\InstallShield Installation Information\{7042DC99-7779-4C5C-A7F2-B9957BFA04EC}\setup.exe" -reboot"C:\PROGRA~2\InstallShield Installation Information\{7042DC99-7779-4C5C-A7F2-B9957BFA04EC}\reboot.ini" -l0x0009

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

1. If a system restart is pending, restart the computer.
2. If the pending system restart requests persists after the restart, then go to start - regedit and navigate to the following location:

32 Bit O.S.:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce

64 Bit O.S.:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\RunOnce

3. If there is a pending restart key under this setting, remove the pending restart key. If there is a "InstallShieldSetup" string, delete it.
4. Go to: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KVS\Enterprisevault\Install. Delete the string: PendingReboot
5. Try to re-initiate the Enterprise Vault installation.

If the issue still persists, please contact Enterprise Vault Technical Support at https://supportenterprisevault.cloud.com/support-home/home for further investigation.

For certain software installations, reboot is mandatory post installation is completed.
This reboot request is added to the registry in Windows O.S. 
Ideally, post-reboot, the request from registry should get cleaned out but sometimes, it doesn't get removed. Due to this, Enterprise Vault Installation gets interrupted.

In Enterprise Vault 11.0.1 or later, a pending system restart request persists even after restarting the computer. This prevents Enterprise Vault from installing.
