Add On to my post numbered 1.....
Just some routine questions that need answers if the uninstall/reinstall does not resolve the problem.
Also, consider doing a free ccleaner run through (regular and registry parts) between the uninstall and reinstall with antivirus and firewalls disabled.
1. What computer operating system is involved?
2. Do you have the latest version of QuickTime 7 installed on your computer?
3. Are you running the programs as administrator (from user account with administrative privileges)?
4. Does the problem exist with or without the antivirus and firewalls disabled?
5. Are you working with Internet connection?
The alternative route mentioned Adobe Photoshop Elements 14 Direct Download Links, Premiere too | ProDesignTools
is OK if the route from Adobe Other Downloads has problems.
However, important if you do have to use it
1. Read and carry out carefully the Note: Very Important Instructions at that web site in order to avoid an Access Denied message.
2. When you read that you will note that it is initially directing you to the Adobe web site to sign in. But, that is all you do at Adobe web site. All the files downloading is done back at web site that sent you to Adobe for the sign in.
