You should start by asking for help in the correct forum... moved from Premiere PRO to Premiere ELEMENTS
What computer operating system is involved?
From where did you download your installation files for Photoshop Elements 13 and Premiere Elements 13?
Do you have 2, one with a .exe file extension and one with a .7z file extension?
If your computer is 64 bit, have you downloaded the installation files for 64 bit? And, if your computer is Windows XP, Windows Vista, or Mac OSX 10.7, stop...Premiere Elements does not support those computer operating systems. If you have a supported 32 bit system, make sure that you have downloaded the installation files for 32 bit.
Please review and consider. Any questions or need clarification, please ask.
