My application runs as a Windows service. During normal execution, some data files are generated in a "data" directory that I create with my WIX install. During an upgrade, I would like to move/migrate those files to the same data dir in the upgraded installation. However, I am running into issues. I am using the "MajorUpgrade" tag as follows:
I tried scheduling later in the process(afterInstallFinalize), but that runs into issues with the service having locks on files during the upgrade. I have combed Stack Overflow and google, and it seems that no one else is describing my scenario. Others have default *.ini files, that the user can potentially edit. However, in my case, it should always be safe to migrate the files, as there are no defaults. They are simply data files that need to be migrated.
I thought I could possibly do this via a custom action, but was not sure how to do it.
Any suggestions would be very much appreciated.
Edit: Apparently using "afterInstallFinalize" works fine for me, i.e. data files are migrated, as long as the user does not change the path during upgrade. If I change the path during upgrade, I get warnings about files being locked, and asking to stop the app using the files. However, it ends up not migrating the files in that case.
Ultimately, I solved my own issue by simply overriding the default dialog behavior, and changing the flow such that on upgrade, I skip over the "InstallDirDlg".

I upgraded from 1.5.x to 3.0.x. During migration the new pages was setup in a separate directory, so the old one could be used without any downtime. After installing all required modules, templates and reorg of some structures I deleted the old page and moved all file from the subdirectory to the root directory. (In addition I change the configuration, so the subdirectory is no longer referenced.) Every thing went well and the user front end seems to be OK. Within the administration pages I have an major issue:
Any page that requires a modal panel (e.g. defining Images for Banners, defining menu items) throws an Javascript error and the page cannot be used:
Uncaught ReferenceError: $extend is not defined modal.js:368
(anonymous function)
Do you have any hint how this issue can be solved?
Thanks.

Try re-uploading all files in the directory:
/media/system/js/
If the error persists or other error occur, consider uploading the Joomla core files again.
Please not that file by file FTP uploads are sensible to error. It's generally more safe to upload a zip and to unzip everything on the server (not to mention it's faster).
For those that aren't fixed by just re-uploading /media/system/js, this error can crop up for people who do an extremely far upgrade (like 1.5.x to 3.0.x mentioned by the poster) because "$extend" has been deprecated (and eventually removed) in mootools.
This means that your old extensions may be trying to use code that no longer exists in mootools. If you can find updates for the extension causing the issue, that's probably enough of a fix. If you can't, then it's usually easy enough to fix on your own...
The short fix for this bug is to change $extend to Object.append
Here is some more info about the upgrading mootools in general, which may help with other issues.

I haven an installer which must run with elevated admin rights if UAC is enabled. This works fine. When I upgrade the app (using the MajorUpgrade element) the app gets uninstalled and reinstalled correcly.
During runtime the app attempts to change some files in the program files folder which places copies them items in the users virtualstore. These do not get removed during uninstall.
During the upgrade/reinstall process, is there a correct way to delete the application file copies, for all users, in the VirtualStore?
Files placed into a virtual store are, by definition of who wrote them and when, per-user data files. Such files typically should not be removed during uninstallation. If the files in question are not actually per-user data files, the application that caused them to be written should be fixed to write to a proper location, update them in a controlled fashion, or even not write them at all.
I have a Wix installer which is designed to install (uninstall) a Windows service and another .exe file. When I uninstall the software using this installer, and enabling extra log, I see some error messages about unable to remove my installation folder, although it is indeed empty. The first message that appears on the log is like this:
DEBUG: Error 2911: Could not remove the folder MY_INSTALLATION_FOLDER.
The following errors are all about the same problem. My first guess is of course that there are some resources that were being used during the uninstallation. However, like I mentioned, all components in this folder were indeed removed and this is an empty folder by now. Also, this error is the first error in the log, meaning there was no error prior to removing this folder. For example, from the log I can see a series of FileRemove actions were taken right prior to the folder removal and they all succeeded. So it's gotta be that this folder itself was being used. But I really can't figure out why and what is holding this folder. By the way the software was indeed uninstalled since the final product removal returns 0 and every thing related to our software was removed (Windows service list, shortcuts, registries...) excepted this empty folder. It is not crucial but we definitely don't want to hear from our customer asking about this kind of error anyway(they are using auto-installation and the log is by default enabled and checked)
Please help. Thanks!
Possible causes:
Other process is locking that folder. Use Unlocker to
verify if that's the case.
Some folders have restricted permissions
by Windows (e.g. C:\Windows\system32). Generally, you should avoid creating files under Windows own folders (unless it's required, I.e.: your'e installing a device driver).
Did you properly set folder permissions?
Is it possible to schedule a custom action after a reboot? Here's my predicament.
I have a product to uninstall and reinstall but some of the files are in use by another application at the time of reinstall. This causes problems for the uninstall because the files are in use so I use a custom action which runs a batch file to rename the files in use. This is a bit of a hack but makes the uninstall and reinstall not complain about the files being in use and replaces the files I want.
The reason for doing this is that I'm not allowed to force a reboot on the machine during the installation process but I need to make sure that the files get replaced. So far so good.
This has the side effect of a bunch of files hanging around that I've renamed with a prefix toDelete_fileX.dll along with the new fileX.dll in the folder.
I have another custom action to delete these files which works fine but I can't run it at the end of the installation because the other application still has a handle to these renamed "toDelete_" prefixed files.
At some point in the future the system will be rebooted and this is where I would like the custom action to run to delete the "toDelete_" prefixed files.
Thanks. Neil
Take a look at this property MSIRESTARTMANAGERCONTROL, you can use this to prevent the files in use dialog, combining this with /qn for msiexec will allow you to do it silently.
When it comes to installers, if you start running batch files during the install transaction you are really on your own as Windows Installer cannot track this. Unless there's a really good reason to roll your own CA I would steer clear.
I think in your case Windows Installer will be able to take care of the renames, when you do eventually reboot. If I've understood correctly you don't mind the reboot, its just you would like to schedule this at a later date/time.
You can schedule actions after a reboot by using RunOnce registry key:

However, I think your going the wrong way with this. If you can offer more details about what you need to do (the design or concept), perhaps I can suggest a better alternative.
I have added a config file (myapp.exe.config) that is deployed to the device after installation. But the problem is that this file gets read-only attribute. I have tried adding some stuff in the setup project in "codeINSTALL_EXIT" function. On emulator it works ... it removes the read only attribute, while when installing on the phone the attribute stays.
SetFileAttributes(szPathConfig, FILE_ATTRIBUTE_NORMAL)
Any ideas?
It's not completely clear from your question how the file is getting deployed (though I think from a CAb only). Things to check/know:
If you install via CAB, but then deploy from Studio (i.e. Debug) the file will get overwritten and the file studio pushes may well be read-only, especially if your SCC mechanism locks local files that aren't checked out (like VSS does).
When you build a CAB file, the file attributes get inherited from the source, meaning that if the file is read-only on the PC when you create the CAB, it will be read-only coming out of the CAB. One woudl think that the EXIT of the installer would be late enough to alter the attributes, but I've never tested it. Following your current path, you might check that the attributes before setting and also check to see if the Set call is actually succeeding. Personally I'd just make sure all files were read/write enabled before building the CAB to avoid the whole problem in the first place.
