Problem:

Error: "Unable to Build Core Server Activation File" when activating the core server.

Solution / Workaround:

Delete all temporary files

1. Check That you have plenty of disk space available for the drive that hosts "\Program Files\LANDesk\Authorization Files".
2. Navigate to "\Program Files\LANDesk\Authorization Files" and delete all the files in this location.
3. Navigate to "%temp%" and delete all the files in this location.
4. Navigate to "C:\Windows\Temp" and delete all the files in this location.

Make sure correct certificate is being used.

1. Check this registry key: HKEY_LOCAL_MACHINE\SOFTWARE\LANDesk\ManagementSuite\Setup - Certname
2. Verify if the "Certname" from above matches the certificate name in "\Program Files\LANDesk\Shared Files\Keys". If not, adjust the registry to show the proper name. NOTE: The certificate name will not have the file extension in the registry
3. Check that "protect.ini" is referencing the correct <hashname>.0 file and that .0 file has the correct core server name.

Replace ldpgp

1. There are 2 files that you would replace; ldpgp.exe and ldpgp.sig. These files are used to encrypt the license files and can sometimes become corrupt.
2. Replace these two files with the ones from the installer. Here is the location from the 9.6 flat installer: "\LANDeskSoftware960\LANDESK\LDMS\Program Files 64\LD\MS\_non"
   1. ldpgp.exe - \Program Files (x86)\LANDesk\Shared Files, \Program Files\LANDesk\ManagementSuite
   2. ldpgp.sig - \Program Files\LANDesk\ManagementSuite
