Subject: Re: [WiX-users] Always change the product code?
Hi Alex
Thanks, this helps a lot!
Three follow-up questions (I'll go on to try-and-error that - but maybe you
know the answer straight away).
1. will UpdateVersion/ @MigrateFeatures="yes" schedule the MigrateFeatureStates
action automatically or do I need to manually schedule in
InstallExecuteSequence?
[Wix will schedule MigrateFeatureStates for you regardless of the value of
@MigrateFeatures. That is easy to verify. Just open your msi file with Orca
tool and see what actions are in the InstallExecuteSequence and
InstallUISequence tables.]
2. will MigrateFeatureStates also migrate the Feature/ @ConfigurableDirectory
or do I need to add RegistrySearch plumbing?
[My understanding is that migration process affects the installation state of
the feature only unless the same feature in another product is set to
INSTALLSTATE_ABSENT or INSTALLSTATE_ADVERTISED. I would worry about migrating
features only if I share features in my product with other products.]
3. ist there an easy way to convert your "PreventDowngrading" to a warning (UI
only) instead of an error/abort?
[Instead of running custom action type 19 run custom action of your choice
which will show a message box. If the user chooses to continue an
installation, return ERROR_SUCCESS/msiDoActionStatusSuccess. To prevent
downgrading - return ERROR_INSTALL_USEREXIT/msiDoActionStatusUserExit. Error
codes: http://msdn2.microsoft.com/en-us/library/aa368072(VS.85).aspx and
http://msdn2.microsoft.com/en-us/library/aa371254(VS.85).aspx]
Many thanks again,
Mark

Hi Mark,
Major upgrade (http://msdn2.microsoft.com/en-us/library/aa369786(VS.85).aspx)
is the easiest of upgrades to implement. The only downside, I can think of, is
the fact that it is a complete reinstall of the product, although by carefully
scheduling RemoveExistingProducts
(http://msdn2.microsoft.com/en-us/library/aa371197(VS.85).aspx) you can
minimize how many files will be deleted/copied during upgrade.
Here
(http://blogs.technet.com/alexshev/archive/2008/02/15/from-msi-to-wix-part-8-major-upgrade.aspx)
is my own understanding of how major upgrade can be implemented. To make it
work *in WiX*, you need:
- Change Product/@Id, Package/@Id, and Product/@Version (incrementing
the third field only is fine);
- Never change Product/@UpgradeCode;
- Make sure that Product/@Language is listed in Package/@Languages;
- Add records to Upgrade table;
- Schedule RemoveExistingProducts in the InstallExecuteSequence table
I have not tried to remove downgrade prevention support, so you can play with
it to check if downgrade will be allowed. I don't see why it would not since I
had to go extra mile to prevent it.
Regards,
Alex

Subject: [WiX-users] Always change the product code?
Hi
After having read about all the gotchas of minor upgrades, including the
necessity for msiexec command-line args, I think it's best (in our case) to
always change the product code and be sure to always get a clean install.
I expect it results in more file deleting/copying activity than would be
necessary, but that's ok.
Is there any other downside I should be aware of?
Can I still only change the third field of the product version number?
Is it true, that this way I can even perform a clean downgrade, if necessary?
Is there a good example for <Upgrade> and <UpgradeVersion> ?
Thanks,
Mark
