HolmImpulse on Windows 10.
For reference.
I recently rebuilt my laptop with a new SSD and installed Windows 10 from an image downloaded from Microsoft. The classic "Clean Install." But I found that HolmImpulse would not install, lacking the .NET 2.0 framework. I installed .NET 6, but Holm didn't like it.
Some digging found that .NET 2, 3, 3.5 are already on Windows 10, but they need to be turned on or activated.
To turn on .Net 2 & 3 in Win10 go to the control panel and look for Windows add-ins. Turn on .NET 3.5 (2 is included) HolmImpulse will now install and happily run. I use the 32 but version of Holm, because I've found it more stable than the 64 bit version.
