Installationsfehler vcredist_x86.exe

[MSCom]

Hallo,
ich habe windows 10 und möchte ein PDF-Converter installieren. Dieses verlangt als Voraussetzung. Visual C++ Redistributable for Visual Studio 2012 (x86) update 4. Ich habe die Dateien bei Microsoft heruntergeladen (vcredist_x86.exe) und ausgeführt. Die Installation bricht mit "schwerwiegender Installationsfehler" ab.
Anbei das Installationslog. Wer kann mir helfen?
Gruß Jürgen
