What computer operating system is your Premiere Elements 11 running on? For now I will assume either WIndows 7, 8, or 8.1 64 bit.
Are you running Premiere Elements 11 from a User Account with Administrative Privileges and with Run As Administrator applied?
Do you have the latest version of QuickTIme installed on your computer with Premiere Elements 11?
What is your export choice and does it make a difference if your Export Save In location is the desktop or to Video Folder in Documents?
We will talk about other troubleshooting once we get the basic information asked for above.
My operating system is 8.1 64 bit. I run this Program as Administrator. I don't have QuickTime on PC. It doesn't make a difference .
QuickTime is a requirement for Premiere Elements (any version). Please download and install it so that we can continue this troubleshooting. Among other things, without QuickTime installed, you will not have QuickTime presets in Publish+Share and will not have available to you codecs supplied by that player.
Please right click the Premiere Elements 11 desktop icon and apply Run As Administrator. Please review computer permissions..
In the meanwhile, please reply to all the questions, including
What is the description for your export choice and does it make a difference if your Export Save In location is the desktop or to Video Folder in Documents?
What is a description of your computer resources?
Please consider and supply details need to help us help you.
We want you to succeed.
