virtualbox.org

Hello,

I've just received my new labtop Toshiba, windows 8.1, Intel Core i5, 6Go RAM.
I want to install VirtualBox (download here) release 4.3.4-91027-Win, but I always receive the same message : This software version does not match your PC, check with the software publisher !!!

Could you help me?

Could you post a screenshot of the error?

Don't know if this will work but it is simple enough to try.

Right click the install file and select "Run as administrator".
