Allow Software with Invalid Signature to Run

By default, windows blocks the installation of signed code if it has an invalid digital signature. Code with invalid signatures cannot be installed. The user only sees one prompt per page per control. Internet explorer places an ellipsis on the text, when the text that is given for the application description, file name, or publisher name is wider than the dialog box in width. This helps indicate to the user that there is more text that they are not seeing and they were being forced to install without the signature.

Steps to Follow

  • Open Internet Explorer
  • Click Tools>Internet Options

  • Go to advanced tab

  • Check off Allow software to run or install even if the signature is invalid and then click OK to save the changes.
  • Now you will be able to run software without Signatures
Registry Tweaks 
  • Click the 'Start' button, and select 'Run'. In the resulting dialog box, type 'regedit'.

  • Next, go to <b> [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Download\] </b> and right click on the DWORD value 'RunInvalidSignatures' and select 'Modify'.

  • Finally, set the value data as '1' to and click 'OK'.
