hi
I'm wondering whether there is a way in C# to be able to see whether a
program has been installed or not?
I want to create a distributional executeable that will have a few
components and show which has been installed already and if it hasn't
been installed then allows them to install it, also not allowing them
to install a certain package until dependencies are installed...
I tried to figure how to do this with a package creater but couldn't
find one to do what I want as I already have the .msi files I want to
distribute, so I just want a simple frontend and not mess around having
to redo it all.
I know how to run the files with C# and see when they're completed...
but want to make sure that its also in Add/Remove programs first before
continuing with anything else that depends on that package.
any ideas?
thanks

You don't have to look at Add remove programs, its just a list of programs
installed. I believe there is a list in the registry for this list. This
gets update everytime you run a MSI. I can't remember the exact location of
the list...
Also another note.. the MSI packager with VS.NET 2003 is powerful, you can
write custom Actions and do things before Install or after Install.. the
codeproject.com has a sample I believe.

I have a Python program that is built on an infrastructure of quite a
few other programs, but I would like to create a standalone nonetheless.
It doesn't necesarily have to be its own executable, although this is
the most attractive option - it could just mean distributing the entire
python distribution with it in an installer or something.
However, here is what I have called in my python file:

When I create an install package, all I see is a folder Icon in the
Add/Remove programs. I have set the AddRemoveProgramsIcon property in
my install package, but that doesn't do anything. I have created
packages before that worked correctly, but not anymore. I have even
tried installing this to different machines, but there was no change.
Is there a different property that has to be set for this icon to be
displayed?
Thanks in...

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,...
