wyUpdate .NET 3.5 requirement breaks my installerAnswered

wyUpdate.exe needs .NET 3.5 to run.

I have my installer set to run wyUpdate.exe automatically after my install, which fails silently if .NET 3.5 is not installed on the customer's system.

So I have to tell my customers:

1) Navigate to program folder where wyUpdate.exe is installed

2) Double-click wyUpdate.exe to run it

3) wyUpdate will recognize the need for .NET 3.5 and initiate download and install

4) Wait for .NET 3.5 to complete install

5) Tell customer to manually launch wyUpdate.exe

I feel like I'm dragging my customers over broken glass to do business with me.

What's the fix for this?
