Hi All,
This is my first message on this forum. I'm working on a project where i need to create custom installer class, which checks for .NET Framework and SQL Server 2005 before installing, if not found then i need to install the Framework and SQL Server 2005.

What i need to know is how can i check whether framework is installed or not(apart from checking in registry).. is there any way ??

If not installed then how can i install the framework while installing the application ??

Please suggest me a solution how can i achieve this ...

Thanks & Regards

Well, you can't check for .NET framework into an installer class: the class will need the Framework to run, so it will crash if there is no .NET installed.
To do what you want, look for Launch Conditions.

Right click on your setup project and press Properties, a window will open. Then, click on the Prerequisites button.
You will now see a list of packages that your application can depend to, check the ones you want to use and select Download prerequisites from the same location as my application to copy them in the output folder thogether with the msi file and Setup.exe.
If you have Sql Server installed on your machine you should have a Sql Server entry in the list, otherwise, look here.

Probably because not express versions of Sql Server are not freely redistibutable (you will need licenses for each machine on which you install it).
If your application is to be distributed on several client machines, then I suggest you to use Sql Server Express.

If you have problems with BMG, you should address them to this discussion page.

I assume you're talking about injecting?
If so, read this article:

http://www.codingthewheel.com/archives/how-to-inject-a-managed-assembly-dll[^]

and - you can create a dll in c# that just contains enums, which would give you a dll without any "classes"......
