PowerCMS2 Solution files instead PowerCMS Builder?

I like the fact that with the PowerCMS solution you can put all the files in a subfolder. I would like to be able to use other solutions and extensions without any conflict. I want to use Framework Builder, Ecart, Form Builder, Security Assist and DataAssist as well as PowerCMS in this site.

I own one copy of PowerCMS2 which I am using on another website. I also own PowerCMS Builder.
Can I just install the solution files on multiple websites instead of using the builder?
Will my PowerCMS2 code allow me to do this since I own the CMS Builder as well?

I know that I will have to copy the developer notes into the code on my pages but that is not a very big deal.

Not having the ability to install into a subfolder is a definite drawback to the extension!

the CMS files of power CMS builder are located in the configuration folder. for help finding the configuration folder, see the common installation issues pdf:
common_installation_issues.pdf

then go to /configuration/shared/webassist/PowerCMS/CMS you can manually copy the CMS files to your site to install it to a subdirectory, and use it just like the PCMS Solution.
