I am having trouble with the SEP installation on Windows 7.  It gets part way through, and then says that the installation was interrupted.  I have read several posts and tried what they have suggested without success.  I have disabled user account control, installed LiveUpdate, and then tried SEP with the same result.  If I try to install again, it says there is a pending installation.  Below is a copy of the 15 lines above return value 3 of the installation log.  I think these values are from when I tried to install SEP the second time.  I deleted the log, rebooted the machine, and tried to install SEP again, with the same result, except that it did not create a log file.

Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\ and delete the PendingFileRenameOperations registry value from the right pane

Hello,

It is recommended to upload the SEP_Inst.log file to us so that we could understand the root cause and assist you.

In your case, follow the steps provided below after you backup the registry enteries.

1. In the registry, navigate to:

   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\ 

2. Back up the registry key.
3. Delete the PendingFileRenameOperations registry value from the right pane.
4. Install the software without restarting the computer first (Restarting the computer may result in the registry key being placed back in the registry before installation.)
5. Restore the registry key from the backup location.

Note: If you do not find the PendingFileRenameOperations registry value in the location above, this error message can be generated if the PendingFileRenameOperations registry value exists in the following location(s): HKEY_LOCAL_MACHINE\SYSTEM\CurrentSetXXX\Control\SessionManager\
