Let's go through each of your 4 issues to see if we can separate them out:
1. In skype my partner can not hear any voice from me, but I can hear voice from my partner.
You need to check if your computer's microphone is picking up any sound (I assume you are using a laptop--can you tell me what model it is?). Here is an article that explains how to check if your microphone is picking up any sound, and a few ways to troubleshoot: http://www.onlinemictest.com/microphone-settings/windows-7
2. Tried to open a mp3 file but a pop up window said "Server execution failed"
I believe this issue is related to Window Media Player. To isolate the issue, I would download a free media player like VLC (http://www.videolan.org/vlc/download-windows.html
). You can select the last button "Zip Package" if you don't want to install VLC and just want to try it temporarily. Open an mp3 file in VLC and see if you have any issues.
3. when I shut down another message appeared but I do not remember what it said.
Sorry, mind-reading is not part of my skill set
4. when I opened a webm video file, a warning appeared: MPC-HC could not render some of the pins in the graph, you may not have the needed codecs or filters installed on the system.
This error is from a program called M
lassic - H
). The error seems to indicate that you don't have the right codec/filter to play that file. I would suggest following the same advice I gave for #2, try opening the webm file in VLC and see if you have any issues.
