It is.
Turn On the automatic updates, and wait.
Yesterday i read about the new download (5735) , and this
afternoon 17:00(I'm in Spain) I get the announcement. I
download from last week (5733) to "5647".
Inmediatly I download manual, and get 5735.
I have V. 1.0.614 with the definition (actual) 5735.
Don't forget to Empty your IE cache and your other
temporary file folders, eg: c:\temp, c:\windows\temp or
C:\Documents and Settings\<name>\Local Settings\Temp (the
path to your temp folder will change depending on your
name) - sometimes programmes can be hidden in there -
watch out for mysterious *.exe files or *.dll files in
those folders.

before you accepet the download.
The 5735 is holding, without problems.
Good luck
