This App has been blocked for your protection
Microsoft has recently made changes, through operating system updates, that prevents many software programs created prior to January 1, 2016 from being installed on a computer with the latest versions of Windows 7 or newer.
ProSelect versions 2015r2 and earlier are affected.
These increased security requirements invalidate SHA -1 code signing certificates with expiration after January 1, 2016. These certificates are digital signatures attached to software that confirms that the downloaded installer file is from a recognized developer and has not been tampered with since it was originally built and signed by the developer.
If you see the message "This App has been blocked for your protection" when installing ProSelect_Setup.exe then likely you are trying to install a copy of the ProSelect installer which contains a code signing certificate which was acceptable at the time of the software’s development, but is now rejected by Microsoft.
If you are registered for ProSelect 2015r3.x or newer, then the easiest solution is to download the latest ProSelect Installer (at least version 2015r3.5) and install that since these versions have been updated to a new SHA -2 code signing certificate which Microsoft now requires. If you downloaded this version before Feb 14, 2016, you should download it again.
If you are trying to install a legacy version of ProSelect, you can install ProSelect using the method below. This process should allow you to install other older software programs affected by this Microsoft change as well.
Run as Administrator from the command prompt
The ProSelect installer should start running so you can complete your installation.
The above solution was one that we found that worked (most didn't) from the suggestions in this YouTube video.
Run Command Prompt as Administrator on other Windows versions
Windows 7 (and Vista):
"Windows Protected Your PC" Message
In Windows 10, there is a new protection option called SmartScreen which is part of the new Edge browser. The first time you try to install ProSelect you may see this window below.
In text that's almost invisible until you mouse over it, you should see "More Info" at the bottom left. Click on this to see this window:
Then click the Run Anyway button.
After you have installed ProSelect once, Windows appears to remember that the software is OK and will let you install any updates later without having to go though this procedure again.
