Can koreader install on Pocketbook Era Color?

I just got my new Pocketbook Era Color and I am very interested in trying out koreader. Is there any reason this shouldn't work?

I have downloaded the pocketbook zip file, unzipped, then placed the files in my device's memory. When I click on apps, there is an option at the bottom titled @koreader. Whenever I click on this app, it stalls for a few moments and then does nothing.

If anybody could help me here, I would greatly appreciate it.
