Cant install Indesign cs6 on macOS Sierra 10.12.4

Hi,

I Can't seem to be able to install Indesign Cs6 on my Macbook running Sierra 10.12.4. Photoshop and Illustrator has been running since before but when I download InDesign cs6 and start the installation, a message appears stating "Install-software can't start. A file MIGHT be missing. download Adobe Support Advisor to troubleshoot. And i can't find any info about this anywhere..

Does anyone know what might be wrong?

Thanks,

Eric
