Since we will be going to switch to doing *.msi installers, I'll post what I have learned while doing non-TortoiseHg Windows installers (this is in no way restricted to using WiX):
Windows installer packages must have product versions in the form 999999.999999.999999.999999 (A) (B) (C) (D) That is: 4 groups of digits. No other characters are allowed. It is possible to specify string version resources, but these are ignored by Windows Installer (visible in the properties dialog of an exe or dll). Windows Installer only respects "binary" file versions (as noted above). Windows installer ignores the fourth group (D). This means, at least one of A, B or C must be counted up when publishing a new, regular msi installer for a product, intended to replace all "previous" installer versions ever published. Otherwise, users will get an error message of the form "The same version of this product is already installed" and installation is refused, meaning they have to manually uninstall before installing the 'update' (Windows Installer will notice that the two installers are different by looking at a GUID in the msi, but it will not be able to tell which one is "newer"). Windows applications usually count up D when doing a new build. So if a Windows application pushes out a broken 0.9.2.? release, they have to name the fix 0.9.3.0 (or higher). Doing a 0.9.2.1 to fix 0.9.2.0 does not work, because Windows Installer ignores the fourth group when considering updates. ------------------------------------------------------------------------------ The Planet: dedicated and managed hosting, cloud storage, colocation Stay online with enterprise data centers and the best network in the business Choose flexible plans and management services without long-term contracts Personal 24x7 support from experience hosting pros just a phone call away. http://p.sf.net/sfu/theplanet-com _______________________________________________ Tortoisehg-develop mailing list Tortoisehg-develop@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tortoisehg-develop
