Can we assume that you have Premiere Elements 11 and are trying to install it on Windows Vista 32 or 64 bit?
Can you install Photoshop Elements 11 from this same installation disc that you tried to use for Premiere Elements 11 installation?
When you purchase the bundled Photoshop Elements and Premiere Elements, typically two discs are in the bundle. One is for Windows and one for Mac. Any chance you picked up the installation disc for Mac?
Sorry. It is Premiere Elements 10. And 32 bit.
I am using the correct disc. I also attempted to dowload a free trial of elements 11 to see if I could get that to work but faced the same problem.
Your problem with the Premiere Elements 11 download blows the following question away, but I will ask it anyway.
If you purchased the bundled Photoshop Elements 10 Premiere Elements 10, how many discs did you receive. It should have been five. And, with Windows Vista 32 bit and Premiere Elements 10 in the equation, you should have been using the disc labelled 1 of 5. Was all of that the case?
What service pack do you have for your Windows Vista 32 bit? And, do you know if your laptop's processor has SSE2 support?
