Solution Method 1: Unblock HTML files
- For SOLIDWORKS Full Installer that has done download and is in Zip file format
1. Unzip the SOLIDWORKS Installation Manager files
2. Browse to the downloaded installation file location <downloads>\sldim\lang\english\HTML
- In this case my downloaded SOLIDWORKS 2021 SP0 was in SOLIDWORKS Downloads, so I will go This PC > Documents to find it, and open the respected files as stated above

6. Re-launch the SOLIDWORKS Installation Manager process
Solution Method 2: Use other extraction tools
If your installation files are in a compressed ZIP file that requires extraction, some applications can cause blocked files. Using third-party extraction utilities like 7-ZIP can increase the likelihood of success.
Solution Method 3: Reset Internet Browser
Try resetting your Internet Browser settings to default, close the browser and re-launch the SOLIDWORKS Installation Manager.
