With Windows File Explorer, navigate to: C:\Program Files (x86)\QPS\QINSy 8.1\Geoid (your QINSy installation folder location may differ)
Look for the EGM2008.BIN file.
If it is present, skip to the 'Copy EGM2008' section below
If it is not present, see the 'Download EGM2008 Install File' section first

Download EGM2008 Install File

In a web browser, navigate to the QINSy download page: QINSy. Login.
In the table at the bottom of the page you will see an entry for the 'EGM2008 model', click the download button in that row.

Run the MSI file to start the installer.
The installer will place the EGM2008.BIN file in your QINSy geoid folder C:\Program Files (x86)\QPS\QINSy 8.1\Geoid (or similar).
