New SDK manager refuses to install

Hi, the SDK manager is outdated and it says it needs to be installed the new version. Ok, I click me through the installation process but at the end the installation fails with following alert:

A debugging check in this application has failed

../../src/msw(dib.cpp(134): assert "hbmp" failed in wxDIB::Create(): wxDIB::Create(): invalid bitmap

What can I do to get that beast running again?
