Anyways SAP is not supporting, can I get it directly from Adobe?

Hello,

Now in the market we have Adobe Live Cycle designer ES4, can I do below,

1) Install Adobe LC designer ES4 in my desktop by buying directly from Adobe

2) I will develop the form on my desktop (not in SAP's SFP tx), say I will name it as MY_Z_LC_ES4_MOBILE_FORM_FOR_USER_INPUT

3) Then, I will go to SAP's SFP tx --> Menu ---> Utilities ---> Download / Upload option

4) Here I will UPLOAD the MY_Z_LC_ES4_MOBILE_FORM_FOR_USER_INPUT from my desktop into SAP

then can I use it, is it works?

Thank you
