Mostly you will have trouble with small & minor updates. If a component is being updated, only the file designated as the keypath is checked to see if it is out of date: if it is up to date, all the others are ignored. Those kind of updates are similar to repairs and repairs are likewise affected.
You'll also have difficulty if you want to add or remove files from each component. Once released, a component is immutable (in terms of what files are in it). The only way to update it without breaking component rules would be to effectively remove and install the a new version of the MSI. Understanding the component rules is key in Windows Installer and one file per component makes the component rules easier to work with, which is why it is the recommendation of many people here. Windows Installer can handle 1200 components easily. ComponentGroups and ComponentGroupRefs can simplify managing large numbers of components in the source code. -----Original Message----- From: Alexey Ivanov [mailto:alexey.iva...@gmail.com] Sent: 21 June 2012 08:57 To: General discussion for Windows Installer XML toolset.

A component is the most granular part of an installation, so if the first file in a component exists and is of the correct version (assuming no other file is marked as the keypath) then Windows Installer would consider the component state to be present. Is there a reason you don't want to utilize a component per file? >> >> -----Original Message----- >> From: Alexey Ivanov [mailto:alexey.iva...@gmail.com] >> Sent: Thursday, June 21, 2012 12:17 AM >> To: wix-users@lists.sourceforge.net >> Subject: [WiX-users] heat.exe generate component for files in each folder, not to generate component for each file. >> >> like this >> https://github.com/krab/vacuum-im-wix-installer/blob/master/Files.wxs >> is possible with wix? >> >> if i run: >heat dir install_files -gg -suid -sfrag -srd -out 1.wxs >> >> <DirectoryRef Id="TARGETDIR"> >> <Component Id="libeay32.dll" >> Guid="{846E7E4B-51A3-4023-AF17-EBC5E0E4AEB6}"> >> <File Id="libeay32.dll" KeyPath="yes" >> Source="install_files\libeay32.dll" /> >> </Component> >> <Component Id="libpng15.dll" >> Guid="{3EF0105F-BBA8-4E11-BF71-956403110505}"> >> <File Id="libpng15.dll" KeyPath="yes" >> Source="install_files\libpng15.dll" /> >> </Component> >> <Component Id="license.txt" >> Guid="{ADCF4296-AEAE-4451-B55D-5EDA4ADB4CD6}"> >> <File Id="license.txt" KeyPath="yes" >> Source="install_files\license.txt" /> >> </Component> >> <Component Id="msvcp100.dll" >> Guid="{64035C09-D6F5-40C3-A008-AF9C73014AA7}"> >> <File Id="msvcp100.dll" KeyPath="yes" >> Source="install_files\msvcp100.dll" /> >> </Component> >> <Component Id="msvcr100.dll" >> Guid="{0960591D-EA25-4BB6-B9C8-D622C7A7C5C3}"> >> <File Id="msvcr100.dll" KeyPath="yes" >> Source="install_files\msvcr100.dll" /> >> >> Components for earch file its feature or its msi requirements? >> >> --------------------------------------------------------------------- >> --------- >> Live Security Virtual Conference >> Exclusive live event will cover all the ways today's security and >> threat landscape has changed and how IT managers can respond. >> Discussions will include endpoint security, mobile security and the >> latest in malware threats. >> http://www.accelacomm.com/jaw/sfrnl04242012/114/50122263/ >> _______________________________________________ >> WiX-users mailing list >> WiX-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/wix-users >> >> --------------------------------------------------------------------- >> --------- >> Live Security Virtual Conference >> Exclusive live event will cover all the ways today's security and >> threat landscape has changed and how IT managers can respond. >> Discussions will include endpoint security, mobile security and the >> latest in malware threats. >> http://www.accelacomm.com/jaw/sfrnl04242012/114/50122263/ >> _______________________________________________ >> WiX-users mailing list >> WiX-users@lists.sourceforge.net >> https://lists.sourceforge.net/lists/listinfo/wix-users ----------------------------------------------------------------------------- - Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
