is it possible to integrate into the ‘Show-InstallationWelcome’-function (or any other dialogbox) a hyperlink - something like ‘www.google.com’ - wich the user can klick and get spezial information about the current running installation ?
The dialog box would have to be a RichTextBox or a LinkLabel (PowerShell GUI: How to Create a Link Label using WinForms - TechNet Articles - United States (English) - TechNet Wiki)
In PSADT, the Show-InstallationWelcome function calls the Show-InstallationPrompt function to display the dialog that you see. It could be as simple as changing the following in Show-InstallationPrompt from:
$labelText = New-Object -TypeName 'System.Windows.Forms.Label'
$labelText = New-Object -TypeName 'System.Windows.Forms.LinkLabel '
and properly formating the message you need in the XML file.
If this seems too overwhelming, you should post your request in Issues · PSAppDeployToolkit/PSAppDeployToolkit · GitHub as a feature request.
PS: If you would have posted this in General Discussion - PSAppDeployToolkit Community I would have seen this sooner.
