ok, fully uninstalling .Net 4.5.1 helped.

You should try re-installing .NET 4.5.1.

I had a similar issue. I have been using KeePass 2.27 for many months. Suddenly, upon launch, I received the error

The instruction at 0x771f11e8 referenced memory at 0xffffffff. The memory could not be read.

Following your suggestions, I downloaded .net 4.5.1 and did a repair of .net 4.5.1. I tried the portable version of KeePass. I installed version 2.28 - nothing changed.

I wondered if a repair was the equivalent of re-installing .net, so I uninstalled it (it took a really long time). After it finished, and before I started the re-installation, I decided to try running KeePass -- it ran!

So with .net 4.5.1 uninstalled, the program runs. This makes no sense to me. Does it make any sense to anyone else? I will try reinstalling 4.5.1 next, but I'd like to know what others think about this.

Here is the event log entry:

NET is a very large piece of software and there have been numerous hiccups with updates. MS are not having a good run with updates at present so to find an issue with NET 4.5.1 is not surprising.
