I'm new to deploying .NET apps, so please let me know if any more details are required.
I developed a C# console app in Visual Studio with MySql. This was deployed on 2 Windows 7 machines via ClickOnce Application and works fine. Tried to install in on a Windows XP machine and got the following error:
System Update Required:
Unable to install or run the application. The application requires
that assembly MySql.Data Version 6.5.4.0 be installed in the Global
Assembly Cache (GAC) first.
I've done some googling and I don't think it's any of the issues that have been mentioned – no firewall, no antivirus, on Administrator account with all permissions. I checked C:\Windows\Assembly and MySql.Data.CF.dll V 6.5.4.0 is listed.
Coworker also dug up the following error log:

I was previously getting another error at install,
URLDownloadToCacheFile failed with HRESULT '-2146697211' Error: An
error occurred trying to download
'http://station52/clockworksEXE/ClockworksConsoleApplication.application'.
however, I changed my settings to publish from CD instead of website and it seems to have solved this, but I'm still getting the GAC error.
Any ideas?

A solution would be to include the MySQL dll as part of your application. Set the dll to "include local" and/or "include" under the Publish Application settings.
This way when your ClickOnce app is deployed, the dll is deployed locally along with it and will NOT look for it in the GAC.
Typically, things in the GAC are installed there for other applications to share and as far as ClickOnce is concerned, are usually installed as prerequisites. Not having to include a component with your application reduces the size of your deployment, of course, as well as allowing your application to use that component that is already shared in the GAC.
The problem you are having apparently has something to do with ClickOnce and WinXP and the solution would be to just include the MySQL component with your application and use it locally to your app.
