Toshiba satellite L755D wont run certain programs like skype.

hami, try these things first. Be sure that Compatibility Mode is not enabled or not checked (right-click on Skype shortcut icon/launcher and select Properties >> Compatibility). Then try it. If still nothing, try to Clean Skype Folders/Files

A. Close Skype. Type or enter %appdata%\skype in the Run command, then click Ok. Look for and delete the file named Shared.XML (a fresh copy of the shared.xml file will be recreated when you login, the previous one may be corrupted causing Skype not to run properly). Restart your computer.

B. With Skype not running, Type or enter %appdata%\skype in the Run command, then click Ok. Delete temporary files all the files starting with “temp-“ or ending with “-journal”, and files with extension “.lock” and with size 0 KB . Then reboot your computer.

If you do not already have done this, set IE as your default browser.You can also try to delete temp internet files and clear cache. If possible, also disable or remove any unused or possible corrupted Internet Explorer plugins/add-ons (regardless of the web browser you set as default, Skype uses IE engines).

1.Click Start, click Run, and then type regedit in the Open box, and then click OK.
