Since Skype is one of the most secure communication means, I actually attempted to download it to my system. To my dismay, I received this error during the tedious installation.
Installing Skype failed; code 1638
Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs in Control Panel.
How can I correct the error? Why did Skype fail to install?
