• LaserficheConnectionCore.dll (version 8.0.0.181)

To update Workflow Designer 8.0

3. Extract the contents of the zip file to a temporary location.
4. Drag and drop the updated versions of the files into the Windows Global Assembly Cache at "C:\Windows\assembly."

Note: User Account Control (UAC) prevents you from manually replacing files in the Global Assembly Cache. If UAC is enabled on your Windows Vista or Windows Server 2008 computer, you must first disable UAC to replace the dll. After replacing the file, re-enable UAC.
