Ignore Previously Installed Versions

krose

I have created an Installer using the "Setup Wizard" in Visual Studio.
I've added a custom action to this as a seperate DLL written in C#.
The custom action has to install files from another location on the
network.

Everything is working and going well.

The problem I am having now is that once it has been installed once, I
am unable to install it again as I get an "Another version of this
product is already installed" error message.

As I understand it I can get around this problem by changing the
Product Code in the installer, but this is not possible as the files on
the network are constantly changing and I can not change the product
code and regenerate the installer every time a file changes.

What I need to do is force my Installer to just ignore any versions
previously installed and just proceed as if it is always the first
time.

Does anyone know how I can do this?

Thanks
Kevin

Same request here!
Also - could anyone tell me where the Setup options are documented?

In the propeties of your instal project there are two properties you are
interested in

"DetectNewerIns talledVersion - YES/NO"

and

"RemovePrevious Versions - YES/NO"

There is also a version number property which you'll need to increment so it
knows its a different version.

I am new to this so this could be totally not what you after but have a
look, it seems to work for me.

Thanks. Finally found them documented under 'Deployment Properties'.
Once you know what they are called (as a group) they can be found in the
documentation -- until then -- it's tough sledding...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
