  • 0

I’m trying to make a setup program for an ASP.NET web site. I need to make sure the target machine has sqlxml installed.

I must verify the target machine has the software installed, and if not, launch a .msi file either before or after the main installation.

I’m a complete newbie with setup projects, so maybe this is obvious, but after several hours browsing the web I haven’t found a satisfactory solution. I’ve been reading about WiX, etc. but I’m looking (if possible) for a simple solution.

Thank you both!

I understand an installer can’t run another one. I was thinking in a functionality similar to Prerequisites (in project properties). There I can check a component and it will be automatically installed if it isn’t. I don’t need to do anything else. But, the most important thing for me is that the installation won’t run if it’s not needed.

I also tried the .msm solution, but I couldn’t find any. Maybe I can make one myself? I haven’t tried it yet though.

  1. Looks like you need to ‘chain’ the installs http://objectmix.com/xml-soap/84668-installing-sqlxml-net-app.html

    You can get the redist here http://www.microsoft.com/downloads/details.aspx?FamilyID=51D4A154-8E23-47D2-A033-764259CFB53B&displaylang=en

    CAn you add this as a pre-req for your install? What are you using to build the create the install?

    Edit:
    I had a look to see how you can check of the SQLXML is installed and come across this:
    http://www.tech-archive.net/Archive/SQL-Server/microsoft.public.sqlserver.xml/2005-04/msg00110.html

    The system I am on just now has the following key HKEY_CLASSES_ROOT \ SQLXMLX (note the X at the end), so you might need to do a bit more investigation in to what the actual key is.

    I’m not familer with Visual Studio install authoring but if you can add an entry to the AppSearch and RegLocator tables you should be able to check for the existance of the registry key when the install starts. See here
    http://msdn.microsoft.com/en-us/library/aa371564(VS.85).aspx

    The Reglocator table gives you the option to set a property with a value from the registry if found. You can then use this in the condition on a custom action.

    A lot to put together, but I hope it move you in the right direction.
