I have purchased Adobe Premiere Pro Elements but was not aware about the 64 bit processor. Can I upgrade now and reinstall it? Please help

Premiere PRO is 64bits only... Premiere ELEMENTS comes in either 32bit or 64bit... which did you buy, Pro or Elements?

If you downloaded premiere elements 32 bit version instead of the 64 bit version, you can download the 64 bit file  here:Premiere Elements  13, 12, 11, 10 | 9
