Similar to bug 34593, though this time, none of XP, 2k3, or win7 work. The
installer claims to support 64-bit, according to Microsoft:
Windows 2000, Windows Server 2003 Service Pack 1 for Itanium-based Systems,
Windows Server 2003 x64 editions, Windows Server 2008 Datacenter, Windows
Server 2008 Enterprise, Windows Server 2008 for Itanium-based Systems, Windows
Server 2008 Standard, Windows Vista Business, Windows Vista Enterprise, Windows
Vista Home Basic, Windows Vista Home Premium, Windows Vista Starter, Windows
Vista Ultimate, Windows XP, Windows XP Professional x64 Edition

What I tried:
rm -rf $HOME/.wine
wine64 uninstaller
wine64 dotnetfx.exe

but the installer claims to not support the OS. relay,seh,tid,msi attached.
