I recently install Parallels on my Mac and it asked me if I wanted to install Windows, so I did. Now I can't activate it - it seems that you installed the Windows Enterprise editiion, which is a huge cost - why would you install Windows Enterprise on my computer, when I purchased Parallels for Mac Standard or not give me the option to decide which version of Windows was installed? I spent countless hours downloading everything and getting Windows setup, now it's forcing me to make a huge Enterprise edition purchase or do a complete new install and download and update everything. I can't tell you how angry I am with Parallels right now.
