How to run software if signature invalid
Some software from the web comes with an invalid signature and by default Internet Explorer (Microsoft's web browser), is automatically programmed to stop installing and running it on the Windows operating system. This is a security action that prevents software from threatening or infecting your PC with a virus. However, sometimes you will need to allow such software to install and run. In this case, you will have to modify the configuration as shown in the article below.
For your operating system to allow software with invalid signatures to run or install, you need to change some settings in the web browser options.
You can access these settings either via the Control Panel or Internet Explorer
- To begin, click on Start > Control Panel > Internet Options
- Open Internet Explorer and click on Tools> Internet Options > Advanced
- From there, tick the box next to 'Allow software to run or to install even if signature is invalid'
- Click on the OK button to validate your choice.
- Use a different web browser to download the file, such as Firefox or Chrome, since only Microsoft Browsers (Edge, Explorer) can be picky about certain clerical problems with signatures.
- Choose a different download location (i.e. save in Downloads if you weren't already doing so, or vice versa depending on your system).
- Tell Windows SmartScreen to ignore this warning (View Downloads > Run Anyway). You can find the detailed steps here on the appfluence site.
