Hmm, this is odd - I've ran the installer on both 32 bit and 64 bit computers and never encountered this error.
Translated error message:
This version of %1 is not compatible with the version of Windows you are running. Check your computer's system information to see whether you need a x86 version (32 bits) or x64 (64 bits) program, and then please contact the software publisher.
That
%1 seems to hint at a corrupted download.
Check the installer's hash (you can use
this utility), it should match either of the following values
exactly - if even a
single character is different, your download is corrupted and you need to redownload it again:
