I've just tried to do this as well, and I think the problem is Orca. Just opening logmein.msi and saving it as a new file name results in a drop from 8.somethingMb to 3.2Mb. If I make the changes suggested, the output file is under 2Mb. I think I have figured out the problem you all are having. For the good of all humanity, I shall share my hard gained wisdom ^_^. Camelot_One was close. When you open LogMeIn.msi with Orca and make the correction and then save, the new copy is much smaller. Thats because when Orca saves an msi under a different name, it DOES NOT save the .dat files contained within it to the other file. SOLUTION... Make a copy of LogMeIn.msi, then edit the COPY with Orca. When finished, hit save NOT SAVE AS.
