I am currently running 2009 SP03 on my machine. I happened to
open the "Add or Remove Programs" application recently while trying
to clean out some old programs. I noticed four entries for
Solidworks in the list. 2008 SP05, 2009 SP0, 2009 SP02.1, 2009
SP03. Are all of these necessary? Could I remove all Solidworks
entries that are not 2009 SP03? Are there important files found
under the other entries that should not be removed? Any info would
be appreciated. Thanks!
When updating to a newer service pack, you are given the choice at installation whether to update (overwrite) or create a separate service pack install. It sounds like you have been selecting the latter.
