I have a situation where we are releasing a new version of our application, and I was wondering how other people handle the situation where they have a datafile and opening/editing that file.
In the previous version of the application users could make a backup file which contains all the necessary parts of the system to transport and restore that file onto another system. Except the file contains no version information.
If the user uninstalls our old version and installs the new version, then these backup files work perfectly.
If the user upgraded to our new version of the application, and also leaves the old version installed then the backups that they took previously when they open (via Double clicking) then they open in the new version BUT the user probably expected them to open in the previous version.
Which of the following choices would be the nicest to the user?
Open the file with the new version and leave it be, they installed the new version so that's life
Present a dialog box showing that they have 2 versions installed and what version do they want to open the file with
If the file is from the old version, automatically launch the old version from the new version passing across the same command line parameters that came in.
If the file is from new version, open new version.
If file is from old version, show dialog box to select

After I instaled extension in typo 3 version 4.5 I can't log in to backend, my page is blank and after I try to go on http://mydomain/typo3/install/index.php I get this message :
The Install Tool is locked.
Fix: Create a file typo3conf/ENABLE_INSTALL_TOOL
This file may simply be empty.
For security reasons, it is highly recommended to rename
or delete the file after the operation is finished.
If the file is older than 1 hour TYPO3 has automatically
deleted it, so it needs to be created again.
Installing any extensions in such an old TYPO3 probably will kill your installation, as any modern extension is incompatible to the old sources.
Modern extensions have namespaces, autoloader, use API classes and functions unknown to the old installation, maybe even use PHP7 features unknown to the old PHP which is needed to run those old TYPO3.
now for your cleanup:
For entering the instal-tool do as the message indicates:
create/update that file and then you can enter the install tool.
but in 4.5 you will not get much help to get the system running again.
you must disable the malicious extension:
in the file typo3conf/localconf.php you need to delete the extension key from the list of installed (active) extension. For this you can use any editor. One is build in the InstallTool.
After that you need to remove the cached version of the localconf.php: remove the temp* files in the folder typo3conf/.
Now your system should work again (but still might be unclean).
you should remove the extension (typo3conf/ext/extensionkey).
Maybe there are new tables and fields in the database. Therefore do a database compare in the InstallTool.
There is no "check for updates" when using the standalone/no install version.
What is best way to update a standalone version without losing settings etc.?
According to my experience (VSCode in a standalone .zip file uncompressed in D:\ using Win7 OS) you just need to download and uncompress the archive containing the new version (v 1.41.1).
When you run Code.exe in the new folder, your settings file is used and everithing is OK. (then, when you are really really sure that it is everithing OK, you could delete the old version).
If you changed the default settings file location, take a look at https://code.visualstudio.com/docs/getstarted/settings#_settings-file-locations
From the official doc it says when downloaded through zip file, one has download the release manually for each update and place the unzip version inside the Program files (Windows).
According to the special portable page all the settings, plugins, etc. of the standalone version
are stored in the data-folder. So assuming you called your vscode-folder vscode:
download the new version
unpack to vscode2 folder adjacent to current vscode
move data folder from vscode to vscode2
delete old vscode-folder
rename vscode2 to vscode
done
P.S.: Current portable versions notify about new version, but clicking on it leads to download, so above list still applies.
Edit 2020/08/04: To make a "normal" install portable one just needs to create the data folder inside the installation/unpack directory of VSC.
To download the old archive, replace user|system with archive in the URL.

How can I create script version update function like in datalife engine cms ? For example customer has version 1.0 and I have created version 1.5. And I want the user to be able to update the script version directly from admin panel. How can I do it ?
Notice: This is my own solution.
#Guilherme Soster has provided the basics on how to do it. However if you do not want to do it yourself you can check my php-updater solution. You can define what you want to add (overwrite or add) and delete as well as scripts you want to run in a YAML file.
well, basically you'll have to store the user system's version in some config file or database and have a server where you keep the latest version of your scripts.
Then when the user request to check for updates (or each time that the software runs) your update script should hit the server and get the latest version number, compare it with the one your user has stored and if the user one is inferior the script should download the new scripts from the server (usually to a temp directory). Now all that the update script has to do is remove the old scripts and move the new ones to the directories where they belong. Finally the update script should update the version in the confi file/database.
Many thanks in advance, I am using advanced installer 12.1, the scenario is we have already installed application with some custom location feature and is extends the default application location, this installation creates some folders to store temporary files like "Temporary" folder, this folder is used by the application on every minute basis and hence there are some files in this folder, now issue is when i run a new build or try to install the new version of the application, i again select the another custom location, before finishing the installation the installer deleting all the folders installed with older version but not deleting the folders which contains files created by the application e.g the temporary directory above is deleted if it is empty but when it is non-empty it is not removed.
Solution i tried:
1) I used file Removal tool to remove the file, but i think it point the current location and not pointing the older application path.
2) A custom VB script, but again the same issue as #1
3) I tried uninstall cleanup wizard, result #1
Please guide me how i can delete that folder, any help would be appreciated.
Thanks
I've added a custom application to my installer project and use it as recovery tool if something went wrong during update or if the new application data contains any bugs.
So far so good, restoring files and database works, but I can't figure out how to restore the version number. How can I implement this?
You would have to restore the file .install4j/i4jparams.conf in the installation directory. It contains the version number, also the file .install4j/response.varfile if you query installer variables in your code.
