You are uninstalling SMSMSE using the Manual removal script and also following the manual removal steps as mentioned in TECH216606
The Script runs fine but you get an error as in the Screen shot
The error code related to this error is 1722
The above error is caused because the mentioned file " SAVFMSELU.dll" is missing because the SMSMSE folders have been removed by the removal script
In situations like these , please copy the SAVFMSELU.dll file from a working machine it is found in this directory
C:\Program Files (X86) Symantec\SMSMSE\7.5\Server
Now on the target machine where the issue is happening , create the same directory path if it does not exist , and move the SAVFMSELU.dll file
Now run the command to unregister
Unregister SMSMSE from LiveUpdate:
Open a command prompt on the computer where SMSMSE is installed and run the following command:
32-bit OS: regsvr32.exe /u "C:\Program Files\Symantec\SMSMSE\<version>\Server\SAVFMSELU.dll"
64-bit OS: regsvr32.exe /u "C:\Program Files (x86)\Symantec\SMSMSE\<version>\Server\SAVFMSELU.dll"
NOTE: Change the value of <version> to the appropriate version of SMSMSE installed. The following is an example for SMSMSE 7.5 on a 64-bit OS:
regsvr32.exe /u "C:\Program Files (x86)\Symantec\SMSMSE\7.5\Server\SAVFMSELU.dll"
This would Unregister SMSMSE from LiveUpdate and the error would not happen again
