Error 1320 during installation of Draftsight – 2D drafting tool

Hello everyone,
Someone told me about a software, in fact a 2D drafting tool for designing and drafting purposes. It is named as Draftsight. I am trying to install this tool on my PC for days now but I simply couldn't succeed.
I just keep on getting this error message again and again:

Error 1320: the specified Path is too long.

I don’t know what to do? Has anybody of you been facing such an issue? Kindly tell me the solution to this problem. What does this error mean and why does it appear? Please share your views to help me out.
Regards,
Peter
