SoliCall Pro

There could many few reasons causing this error message. It can be that the license file you provided does not exists or can not be read. Alternatively the license file you are using is not valid for this version of SoliCall Pro or it had expired. For more information, check the log file C:\Program Files (x86)\SoliCall\log\errLog.
This can happen if you have more than one microphone/pair of speakers. You need to make sure you have configured SoliCall Pro to the mic/speakers you want SoliCall to work with.  Go to Tools --> Options, and under the subsection Sound Devices choose the right device.
Make sure the option of "Echo Cancellation" is enabled. You can increase the aggressiveness of echo cancellation. In addition, try to turn the volume of your microphone down (by using windows control panel ). Also, make sure that the speaker volume is set to allow you to hear the other person conveniently (not too low, but not too high either).
When you hear echo, the problem usually originates at the far end. We recommend that you ask the other party to: (1) Set his/her speakers’ volume to a comfortable level (not too high). Also, they should try to keep their speakers away from the microphone. (2) The other party should either install SoliCall as well (since SoliCall has built-in algorithms that reduce echo) or use headsets. (3) Activate the option of "Incoming Echo Cancellation" in SoliCall Pro.
Make sure that SoliCall Pro is running.  An easy way to tell is if the icon appears on your task bar. Another issue might be that you are currently adding a speaker. You have to complete or abort the process in order to conduct your call.
During the call, SoliCall Pro creates two files, one with a speaker extension (*.spk) and the other with a microphone extension (*.mic). When the call ends, SoliCall merges them into a single wave file. This operation may take a few minutes, depending on the length of the call. If you provide an MP3 encoder, SoliCall can call it to convert the WAV file to an MP3 one.
That's because you listen to it in mono. Make sure you have two speakers plugged-in and turned-on, and that your settings allow you to hear audio in stereo. Another option is to change the Recording Format to Mono.
Because of software patents we cannot distribute an MP3 encoding software.
When this warning message appears it mean that SoliCall cannot perform echo cancellation because different formats are used for the microphone and speakers. Usually this is caused by different applications that simultaneously use the audio device. If you encounter this problem, please close all other applications that might use the audio device for playback and/or recording and make sure only your VoIP application is running.
This message appears when multiple users are logged-in together on the same PC. This can happen when the Windows "Switch user" operation was used and it kept both the old user and new user logged-in. This behavior is due to the fact that SoliCall Pro is a special application that is connected to the virtual audio device driver. Therefore only one instance of SoliCall pro can be simultaneously executed on a single computer. To avoid this message simply use the Windows operation "Log Off" before a new user log in.
During installation, SoliCall Pro is installing a virtual audio device. On some rare scenarios this operation will trigger an error message from Windows saying something like "a digitally signed driver is required". This message means that your windows version is unable to read/identify our digitally signed driver certificate. Following are few ways to address this problem. If you are running windows 7 then go to windows update and make sure the latest security updates are installed on your computer. If you are running windows 10, take a look at Microsoft's recommendations.
