[kylin] I am a begier and I caot download Adobe Acrobat

Good moing,

I need to download Adobe as I need a program called Trinmar Software: the program is Finman.
This program may help me as I am lending a family member funds to buy a house (a contract for this loan is being drawn up by my solicitor with the house as security) so I need a program that can be used on Ubuntu (I have Kylin on my computer) that will automatically show the amount of principal and the amount of interest and the balance owing on each fortnightly deposit made and carry that amount over to the next fortnight, then the next, ad infinitum, until the loan is fully paid off.
This program (Finman) may be what I need as it would allow me to see (when I enter each fortnightly amount into the program) the principal component and the interest component as well as the balance owing.

But...I need Adobe first and I have no idea how to get it.

Please help.

Thank you from Pey
