Moving Cumulus MX 4 to a 'new' computer
Posted: Thu 06 Mar 2025 10:46 am
A while back I found myself in the position of looking at a reformat and reinstall to upgrade my computer to Windows 11. I waited until I had a clear slot to do it all, and thought all I had to do to move my Cumulus installation was to take a copy of the directory/folder to a USB stick, and then when I had Windows 11 up and running simply copy it to the same location (C:\) and start Cumulus.exe. However it hasn't worked that way. When I create a shortcut to Cumulus.exe, and the double click it I get a flash of a window appearing and then it disappears. There is nothing in MXdiags, and adding -debug to the command in the shortcut does not change that.
So I thought, let's download a new copy of Cumulus 4 and try running that without any of my data or configuration files. The result is the same.
Next port of call was to see if downloading .NET 4.8 might help, but on doing that I was told that my computer was already running a later version.
I get the same result if I run it with admin rights, except I get the Windows dialog box warning me that it may be unsafe to run. But that's what I got with every upgraded installation on my old Windows 10 setup.
Finally, I have a Windows 7 virtual machine, and I tried it on that, but the result was the same. I get the feeling I'm missing something obvious, but cannot find what it is. Can anyone help please. Many thanks in advance.
