I've long had a problem trying to delete a registry key entry, in an effort to remove and reinstall Skype. On my original administrator account I've been unsuccessful.
However, not long after I got my new laptop, I had to create a new administrator account to change the date and time. Under my original account, I got an error saying, "Date and Time: Unable to continue. you do not have permission to perform this task. Please contact your computer administrator for help." With the second account, I was able to change the date and time.
This brings me back to the Skype issue. I un-installed skype, but when I went to reinstall it, there was an error, citing an error in the registry key. When I jumped over to the 2nd admin account, I can install it no problem.
So, there is a problem with my administrator account and its ability to perform and be recognized as a true administrator. Any thoughts or ideas are greatly appreciated!!
