That is an open issue.

Comparing both dll's showes that the newer libgnutls-30.dll depends on some
symbols from the ncrypt.dll system library
DLL Name: ncrypt.dll
vma: Hint/Ord Member-Name Bound-To
1ea260 3 BCryptCloseAlgorithmProvider
1ea280 29 BCryptGenRandom
1ea292 39 BCryptOpenAlgorithmProvider
1ea2b0 65 NCryptDecrypt
1ea2c0 66 NCryptDeleteKey
1ea2d2 76 NCryptFreeObject
1ea2e6 77 NCryptGetProperty
1ea2fa 84 NCryptOpenKey
1ea30a 86 NCryptOpenStorageProvider
1ea326 94 NCryptSignHash
At least BCryptCloseAlgorithmProvider was added with Windows Vista
(https://docs.microsoft.com/en-us/windows/win32/api/bcrypt/nf-bcrypt-bcryptclosealgorithmprovider)
and explains why kmymoney could not be loaded on Windows 7.
I will add a note on the snapshot download page referring to the minimum
operating system requirements. Maybe there is a solution, but I can not say at
this time if it would work with the latest gnutls sources.
Considering that there is no maintenance for Windows 7 anymore and you can do
online banking with KMyMoney, it might not be such a good idea to use this OS
version for it.

That seems to be normal on Windows :-/

That may depend on the way how the libgnutls dll was build. I remember that
there is was an option in the source to use a ncrypt/bcrypt emulation layer to
support older os. Maybe they used that.
