I have downloaded and installed CamStudio, in my case I am using microphone for the sound recording and have not change any default settings by now. The problem is that when I am recording screen video and if it is longer than 15 minutes then I get an error message saying ”File Creation Error. Unable to rename/copy audio file” I have been looking after a solution for the same but I have not yet found an effective solution to fix this out. I have tried uninstalling and reinstalling camstudio several times but it is not making any difference. Is there anything else that I can try out or is there anyone who is aware of this issue and has a fix for it??
