I've got an Acer Aspire notebook with amongs others a mobile intel r 4 series express chipset. Most system requirements will be met as it is using windows 7, has 4gb memory etc. But I'm unsure if my video chip will. System requirements says Intel® Pentium® 4- of AMD Athlon® 64-processor (Intel Core™2 Duo- of AMD Phenom® II-processor aanbevolen). Will cs5 work with my inbuild graphic chip too?
It would have helped if you had mentioned the model to be sure, but my guess is no.
If it does not have two internal SATA 7,200 RPM disks, at least 1200x900 monitor, dedicated video memory, a quad core processor etc. forget it.
List your specs and compare them to these ridiculously low minimum requirements: Adobe Premiere Pro CS5: System Requirements
If you meet those, then you can install CS5. If you want to use the program, you better exceed these requirements by a wide margin.
