Unblock Single File: Zipped Folder Missing Unblock Option

Unblocking installation files is important because if they are not properly unblocked, the SOLIDWORKS Installation Manager can appear broken and blank, preventing installation.

If you are attempting to unzip the SOLIDWORKS fileset, but there is no unblock option in the file properties of the zip file, this guide will introduce methods to unblock the zip files.

Unblocking the 3 HTML Files

Using the Windows PowerShell Application

Unblocking the 3 HTML Files

You can manually unblock the 3 necessary files inside the installation files. There are 3 HTML files to unblock:

• frameset.html
• framesetstartup.html
• header.html

These are located in:
[SOLIDWORKS Installation media folder\sldim\lang\english\html]

All 3 of these HTML files need to be unblocked. This is done by 
Right-clicking each file > Properties > Unblock > Apply > OK

Once these 3 HTML files are unblocked, please restart the installation manager.

Using the Windows PowerShell Application

Note: Please check the file type to make sure you are unblocking the correct zip file by right-clicking on the downloaded zip file and ensuring the file is not set to read-only.

Use Windows PowerShell to unblock a single zip file:

1. Open an elevated Windows PowerShell by right-clicking on the Start Menu and selecting Windows PowerShell (Admin). In Windows 11, this is called Terminal (Admin).
    
2. In PowerShell, type the command below, and press Enter.
   
   unblock-file -path "[full path of blocked file]"
   
   Substitute [full path of blocked file] in the command with the actual full path of the blocked file (with file extension) that you want to unblock. Include the quotations.
   
   Note: Windows PowerShell will move to the next line without error to indicate that the command was successful.
   
3. Go back to the zipped folder and right-click to extract the contents.
4. Run the Installation Manager.

If neither method above has worked to unblock the installation media, and the Installation Manager is still blank, you may need to create a new Windows user profile and unblock the installation and install using that account. Your IT department will be able to assist with the creation of a new Windows user profile.
