Hello,
Action 19:06:41: ShowServiceProgress. Starting services
ShowServiceProgress: incrementing tick
ScriptGen: ShowServiceProgress() script execution failed.
ScriptGen: ShowServiceProgress() reset script failure event.
ScriptGen: ShowServiceProgress() is returning an error (so close to the end!)
CustomAction ShowServiceProgress returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 19:06:41: InstallFinalize. Return value 3.
MSI (s) (34:CC) [19:06:41:270]: User policy value 'DisableRollback' is 0
MSI (s) (34:CC) [19:06:41:270]: Machine policy value 'DisableRollback' is 0
Check this Thread (Almost the same Issue):

Also,
Disable UAC and Windows Firewall and Try Creating a custom setting under the “Client Install Settings” options to not use “Add the program to the Start Menu”, leave this unchecked.
OR / AND
Deploy a client install package with "Remove all previous logs and policies, and reset the client-server communications settings".

If the install is successful, manually create the shortcut on the desktop that points SymCorpUI.exe.
Hope that helps!!
