Error Message: Error while unpacking program, code LP5. Please report to author

This is a general Windows error message that could occur for any of the following reasons:

  • the file has been corrupted during transit – you can download the zip version instead from the Locklizard web site to eliminate this issue
  • an anti-virus or anti-spyware application has corrupted the file
  • you don’t have Windows administrator rights to install the Viewer
  • you are using an unsupported OS such as Windows XP – only Vista and above is supported
