I have had the same problem with the installations of the latest
Limewire versions, as numerous other users.
I have tried every possible solution to get by the error 1603
" Can not uninstall the previous version.." but none has worked. I was not able to try the DCOM solution that was described here in the forum, because it looks like that DCOM is not available for my OS; Windows Millenium

Finally I read in the forum that the Multilingual (Pro) version used a different installer so I tried it, and it worked.
