To anyone who can help me,
Today I have done the idiotic thing of accidentally deleting the Windows 7 program that was working very well for my Parallels Desktop app on my Macbook Pro at the 'trash' icon. I was cleaning out and organizing my files. I have tried multiple times to open the program, but I keep on having this window popping up saying that I need to Install Windows or another OS from DVD, I am unclear as to what to do.

I have also tried to use the Support Request to submit by e-mail, but no prevail since I somehow keep on being sent to an error page.
I do not know how to get the Windows 7 program back onto my laptop. I have been frantically trying to find multiple solutions whether I should go and by the Windows 7 software which costs a lot... and I don't really have that kind of money to buy the Windows 7 software. Anyone can you please help me with this dilemma as to how to resolve this ASAP. I mainly use it for Rosetta Stone and if I need to configure any programs that requires the usage of Windows 7 whether it is for school or work.
Would I need to get the Windows 7 software? Are there any alternatives? Would I need to somehow uninstall the Parallels Desktop app and reinstall it?
Please any help would be much appreciated, I feel stupid right now that I deleted the Windows 7 program by accident.
