Skype error- failed to load library dxva2.dll in Windows XP. We have two solutions at this time for XP-users. The first way to solve this error is uninstalling new Skype 7.5 and restoring previous version 7.3.
Another solution to bypass the error message: failed to load library dxva2.dll is the install of Microsoft .NET Framework 3.5. This way is certainly to those who want to experience Skype 7.5 or later version.
