What version of Windows are you using??

It looks like one of 5 things.

1. Windows Installer needs updateing/reinstalling

2. C++ Redistributable needs re-installing :-

3. Update Windows via Windows Update

4. Disable any AV Software while installing the software

5. Redownload the installation files and try again.

Hope this helps. I would have put links to the files that are needed to be downloaded but the forum wont let me.
