NI VISA shared components wrapper failed to install

Hello.

I am trying to install NI 488.2 from a CD, which also includes NI Visa 16.0 and more on a 64-bit windows system. I alerady had this installed, and I removed it in order to re-install again. I removed it using the program, though after removing I noticed I still had IVI Shared Components on Programs and Features, so I removed it manually.

Now, when attempting to re-install, it gives the error "NI VISA shared components 64.0 failed to install". Of course the VISA doesn't work correctly without it.

I don't know what can I do.

thanks for the help!
