Is there something wrong with what I am doing, or is there something else I need to do in order to move the files? I need to move the files to a different folder before installing the newer versions of the files.
My big question would be .... Does Installshield resolve path variables entered directly into the tables like that? To test it I would replace MYSOURCEDIR and MYTARGETDIR with actual hard coded paths to see what happens. Also, you might want to consider using msidbMoveFileOptionsMove for the options.
I've set the option to 1 for msidbMoveFileOptionsMove, but it didn't make a difference.
I can't copy the path into the SourceFolder or DestFolder in the MoveFile table, as it does not seem to accept anything with spaces or \ characters. From what I can see it would only ever accept a path variable.
I just setup a test install to try this out and it worked correctly. I did use Properties like you stated at first and it worked. Did you create a component called Library and is it set to get installed?
