Thank you both. Maybe I should remove the old BIAB through Control Panel? If that works.

My first message was probably confusing. I already have the 2013 version on a hard disk. I tried to install it but the space on the SSD disk was too small. After that I realized what I had done wrongly.

I have all my own files saved in another external disk so I can easily delete all BIAB files. But maybe I copy them to this E drive. I will try that tomorrow.
