Updater created with Inno Setup does not change the application version

I am using Inno Setup to create an application installer (a big file) and an updater, which is just a small file and contains only files which changed since the previous installation/update. This update file also should increase the number of the application version. I followed this document https://jrsoftware.org/isfaq.php#updateinstall, i.e. I set CreateUninstallRegKey=no and UpdateUninstallLogAppName=no

Everything works fine except one thing. The updater does not change the version number in the list of installed applications. For example, if I installed the version 1.1.2 with the installer and then ran the updater which has parameter AppVersion=1.1.3. The updated files get installed correctly but the version in the list of installed application (in Windows Settings) still shows version 1.1.2.

I tried to change to UpdateUninstallLogAppName=yes but this does not affect the version number displayed. When I look into registry, I still can see the number 1.1.2.

Any ideas how to solve this?

Solution

  • You will have to change it explicitly in your script.

    CreateUninstallRegKey=no prevents any updates to HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall.

    As the page you linked to says:

    The update should not create a new entry in the Add/Remove Programs list, or alter the original application's entry.

    You can use [Registry] section entry (as your comment below shows) or RegWriteStringValue function.
