If the DesignR1 suite of apps icons don’t show up, we need to fix the machine.config file in .NET

Checking Microsoft .NET Framework machine.config File

  1. For Act v16, 17 & 18
    Using File Explorer, navigate to this folder: C:\Windows\Microsoft.NET\Framework\v4.0.30319\config\
  2. For Act 2013 & older
    Using File Explorer, navigate to this folder:
  3. Locate the machine.config XML configuration file.
  4. Take a look at the file size and verify that it is more than 50KB. If not, this is likely the issue.
  5. To fix the issue, proceed to a workstation that has a working version of the DesignR1 App on the same database.
  6. Copy the machine.config file from that workstation over to the affected workstation.
  7. Before adding that file to the folder listed above, add ‘old’ to the original machine.config file name.
  8. Copy the new machine.config file into that folder.
  9. Restart Act!.

If that doesn’t fix it, add these steps

  1. Remove the DesignR1 .DLLs in the \plugins folder
  2. Uninstall the application if it’s in the control panel
  3. Delete the dependentdlls.xml file in the \%appdata%\act folder
  4. Reinstall the DesignR1 App
