Applies to:
LoadRunner Enterprise [LRE] (All Versions)

 

Issue:
Remote silent install of LRE Host fails. While performing the silent install of a LRE Host, the following “Windows SmartScreen” message appears:

 

 

This pop-up will stop the process flow and cause the silent install to fail.

 

Cause:
Depending on your security settings, Network Virtualization files can be blocked when downloaded outside of the network. This is done by Windows to protect computers from unverified files and will need to be unblocked to complete the installation.

Remote installations are not supported with UAC enabled on the system. To circumvent this, UAC (User Account Control) must be disabled.

Windows Smart Screen filter will create a popup if enabled during the silent install. This filter will need to be disabled if this issue is encountered.

 
Resolution Steps:
Unblock Executable File Security Properties:

1. Right-click one of the NV installation executable files located in <NV installation path>\Additional Components\Network Virtualization and select Properties.
2. If there is an Unblock check box in the General tab, select it and click OK.
3. Verify that the Unblock check box is gone.
4. Repeat for each executable file in the Network Virtualization folder.

Network Virtualization (NV) files are blocked to protect computers from untrusted files and display a message when downloaded from the internet or FTP site.

Disable User Account Controls (UAC):
1. Open a DOS prompt and Type regedit.

2. Navigate the registry tree to the following path:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\policies\system"

3. Disable UAC by changing the DWORD value EnableLUA from 1 to 0.

 

4. Reboot the machine to apply the registry change (can save restart until end of next section as another registry edit reboot will be required).

Disable Windows Smart Screen:

1. Open a DOS prompt and Type regedit.

2. Navigate the registry tree to the following path:
"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer"

3. Disable Windows Smart Screen by changing the DWORD value SmartScreenEnabled from 1 to 0.

 

Please Note: After the silent install is complete, you can re-enable UAC and SmartScreen by changing the registry values back to their default value(s) of 1.

 

Note: Remote installations are not supported on hosts located behind a firewall.
