INSTALLATION FAILURE - Help!

I successfully installed Verbum 6 on my desktop (Win 7) two days ago.  I am now trying to install Verbum 6 on my laptop (Win 8.1) and am experiencing a failure right at the start.  When I click on the Verbum icon on the task bar here is what happens:

1.  Verbum tells me an update is ready.  Do you want to install it? (I click "Yes")

2.  An installation process seems to extract a file.

3. A Microsoft .NET Framework installation window pops up.

4.  The process stalls/dies within a minute or less.  I left it run all night and it was still in the same spot.

5.  I opened Task Manager and noticed that the Setup Installation process was not using any CPU, very little memory (<1MB), and no disk.

6.  I killed the process. and received the following error.

7.  When I look in Windows Update History I am seeing several updates to Microsoft .NET 3.5 and 4.5 going back at least to February of this year, maybe further.  This leads me to believe that I have the current .NET Framework already on the Laptop.

I can duplicate the process on demand.

Can anyone give me a hand?
