Hello, Well, I managed to overcome this myself. For those who interested in details, please visit my blog: http://ysdevlog.blogspot.com/2008/12/multiple-instance-installations-and .html
I would appreciate any comments. -- Yan -----Original Message----- From: Yan Sklyarenko [mailto:y...@sitecore.net] Sent: Wednesday, December 24, 2008 4:44 PM To: General discussion for Windows Installer XML toolset. Subject: [WiX-users] Multiple instance installations and patches Hello WiX community, I'm just stuck with this scenario and I'd appreciate any hint. I have a product which supports multiple instance installations with the help of instance transforms. In order to make the components data isolated, it is installed to different folders (like best practice guide suggests), and also I apply another transform to change component GUIDs for each instance. Hence, in order to install instance 1 I use the following command line: Msiexec /i MyPackage.msi MSINEWINSTANCE=1 TRANSFORMS=:InstanceId1;:ComponentGUIDTransform1.mst INSTALLLOCATION=... And for instance 2: Msiexec /i MyPackage.msi MSINEWINSTANCE=1 TRANSFORMS=:InstanceId2;:ComponentGUIDTransform2.mst INSTALLLOCATION=... Etc. This works perfectly. Now I'd like to build a patch which then can be applied to any of the instance. I use the "pure-WiX" way of building the .msp: candle Patch.wxs light Patch.wixobj -out Patch.wixmsp torch -p -xi v100\MyPackage.wixpdb v101\ MyPackage.wixpdb -out diff.wixmst pyro Patch.wixmsp -out Patch.msp -t UpdatePatch diff.wixmst The output patch.msp can successfully patch the default instance only. Now, again following the guide, I'm going to populate the Targets property of the patch SummaryInfo stream with the product codes of other instances. Something like this: static void SetTargetProductGUIDs(string mspPath, List<string> productCodes) { using (Database patchDatabase = new Database(mspPath, DatabaseOpenMode.Transact)) { StringBuilder targetsBuilder = new StringBuilder(); foreach (string productCode in productCodes) { targetsBuilder.Append(targetsBuilder.Length == 0 ? productCode : string.Format(";{0}", productCode)); } patchDatabase.SummaryInfo.Template = targetsBuilder.ToString(); patchDatabase.Commit(); } } This really updates the patch file. I can see this in Orca: View - > Summary Information - > Targets field contains all product codes. BUT, when I try to apply this modified patch to other instances of my application (not only default), I get the same error: "The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch." Does anyone know what can be wrong? Any hint... Please, help... Thank you. -- Yan ------------------------------------------------------------------------ ------ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users ------------------------------------------------------------------------------ _______________________________________________ WiX-users mailing list WiX-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wix-users
