Currently Installed Version

We deploy our windows service software with an MSI for the initial install. We are testing the auto updater for patching, and it is working very well. However, when I check the currently installed version through Add/Remove Programs, it still shows the initial release version, even after an update. Also, the file and assembly versions on the EXE show the initially installed version, also. Is this by design or am I doing something wrong?

If it is by design, is there anything I can do during the update process that will resolve these issues?

Hey Doug,

Also, the file and assembly versions on the EXE show the initially installed version, also. Is this by design or am I doing something wrong?

Did you compile the updates with updated version numbers? wyUpdate doesn't change the version numbers of your compiled assemblies, you're responsible for that. So, change the version numbers and recompile your exes.

However, when I check the currently installed version through Add/Remove Programs, it still shows the initial release version, even after an update.

You need to do a little bit of registry editing: simply change the "DisplayVersion" value to the latest version.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\YourAppName

Also, to save time, you can use the %version% variable and every new version you create will use correct version (instead of having to type it each time you release a new version).

Tell me if this helps.

I believe that the assembly version was changed before the release. I will confirm, though.

I will implement that registry change. That is a great tip.

As always, thanks for the quick response.
