With old wine version 5.0 the installer starts, but in current git it says one
has to install .net 4.0

>From a log appears to open regkey HKLM/Microsoft/Net Framework Setup/v4/Install
, and then from what I understand tries compare the values and fails???? 

0024:Call oleaut32.VarBstrCmp(0028d244 L"&h1",00408650 L"1",00000000,00030001)
ret=4fefaa23
0024:Call ucrtbase.memcmp(0028d244,00408650,00000002) ret=64f20c40
0024:Ret  ucrtbase.memcmp() retval=ffffffff ret=64f20c40
0024:Ret  oleaut32.VarBstrCmp() retval=00000000 ret=4fefaa23

I don`t know anything about this VarBstrCmp, needs regressiontest anyway
