  • If the compatibility pop-ups did not happen with Windows 8 then there are compatibility problem with Windows 8.1 – Ramhound Jul 18 '13 at 17:21
  1. Once you have installed the software, right click and select properties.

  2. Select the Compatibility Tab

  3. Select Run in Compatibility Mode, then select the version of windows the software was designed for.

  4. Apply the settings

This should solve your issues.


If you created a recovery partition via Windows, before you installed 8.1 then you could restore your machine. link

You could always factory restore your machine is you are unhappy with Windows 8.1

I don't believe the 8.1 is your issue. You probably would have had issue installing the software in Windows 8 period.


Ms changed the way how the GetVersionEx API works, so some tools run into trouble:

Operating system version changes in Windows 8.1 Preview


The App developer must add the supportedOS ID into the manifest:

<supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"/>

So call the support of the tools.
