Update: December 2014:
When using Skype 6.22 or 7.0 for Windows Desktop, Simkl will not record any audio.
Due to a bug in the Skype API (used by application like Simkl to communicate with the Skype application), any 3rd party recording application is unable to detect when a Skype call starts and stops. The Skype API does not provide this information in the latest Skype 6.22 or 7.0 for Windows application.
To resolve this issue, please downgrade by installing Skype 6.21. After you have done this, Simkl will work normally again.
Download Skype 6.21 from here: http://download.skype.com/msi/SkypeSetup_220.127.116.11.msi
After installing, disable automatic updates in Skype: https://support.skype.com/en/faq/FA12096/how-do-i-turn-off-automatic-updates-in-skype-for-windows-desktop
Skype will provide a fix in the upcoming Skype 7.1 release. Expect this to be made available in January 2015.
We will be updating this article as we receive new information from Skype.
Important: Skype 6.9 and higher will show a warning message when you start Skype that Simkl will stop working in December 2013. This decision has been reverted by Microsoft/Skype. Simkl will continue to work after December 2013!
When you upgrade to Skype 6.9, you will be seeing a message in Skype letting you know that Skype will stop 3rd party applications to access Skype.
Skype have announced that they will remove the Desktop API from Skype for Windows Desktop, Skype for Mac and Skype for Linux. In addition they have announced the decommissioning of SkypeKit, a tookit with which Skype was integrated into hardware devices such as TVs.
The removal of the API will render all Skype add-on products useless. This includes Simkl Recorder for Skype, various hardware products and the majority of other applications. As you can understand, we are not at all happy about this.
As of Skype 6.11 the Desktop API will be physically removed from the Skype application. Add-on products like Simkl will not be able to communicate with Skype anymore. This affects all add-on products built for Skype!
For the time being we recommend to downgrade back to Skype 6.8 until we see how this plays out. Download from here. Important notice: after installing Skype 6.8, disable the automatic update function in Skype (Tools > Options > Advanced > Automatic updates).
We are particularly shocked about this because of the short notice given to Skype users and the fact that Skype is not providing any replacement/successor interface model which will allow us and other developers to further provide the functionality you are enjoying today.
Please consider to sign a petition over at Change.org (and don’t forget to share it too).
UPDATE: A new statement from Skype informs that products providing call recording will continue to work beyond December 2013, until further notice. Further information on the Skype Blog.
To be safe, for the time being we recommend to downgrade back to Skype 6.8 until we see how this plays out. Download from here. Important notice: after installing Skype 6.8, disable the automatic update function in Skype (Tools > Options > Advanced > Automatic updates). More information how to stop automatic updates can be read here.
We will update this article as we have more information. For now rest assured that Simkl will continue to be operational and able to record Skype, just by using the older version of Skype.
