Do you mean download from an Internet site to your computer, or are you trying to install the program on your (Mac or Windows???) computer?
From where are these Photoshop Elements 13 and Premiere Elements 13 purchased downloads coming from - Adobe or an authorized reseller.
What computer operating system is involved?
Are you downloading two files for Premiere Elements 13 - an .exe file and a .7z file or other? What is your computer's default browser?
I have never seen a Premiere Elements download with that "header too long" message for anything downloaded from Adobe.
If all else fails, install Premiere Elements 13 from the following web site and insert your purchased serial number in the tryout installation files.
Be sure to read and carry out carefully the web site's Note: Very Important Instructions in order to avoid an Access Denied Message.
Please let us know the outcome.
