[missing-sync-palmos-talk] Which conduits i need to keep to upgrade to 4.0.2 ???

[Fred]

Hi,

I'm using actually MS 4.0.1 with my Tungsten T3 on OS 10.3.6. and I 
want to upgrade to version 4.0.2 because i got several problems with 
sync with Entourage, palm desktop etc...
I got also a problem with exporting photo from iphoto (progression 
bar's freezing and nothing is exported).

So i wonder which i need to do for upgrading:

1) Do i need to uninstall MS 4.0.1 before installing MS 4.0.2 ?

2) Wich conduit do i need to backup in a folder on my hard disk  before 
installing MS4.0.2 (MAL conduit, adobe reader conduit, docs to go 
conduit, isilo...)???

3) Do you think i should not keep the Entourage conduit and reinstall 
it after the installation of MS 4.0.2 ? Will i need to run the the 
Handheld Sync Installer after the installation of 4.0.2?

4) When i will install the MS 4.0.2, will it install automatically a 
new plug-in in iphoto and itunes or do i need to uninstall manually the 
previous and reinstall them ?

Thank you for your answers...
I'm not speaking english so well, so your help will be very 
appreciated....

Best regards
