Okay. You've extracted this part from the Windows Registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Protexis\Licenses\438839465\Trial]
"Terms"=hex:ae,4d,32,6e,8e,d8,1d,d8,3d,ff,ac,ef,9e,61,d8,84,4f,46,e4,06,e6,93,\
86,73,3d,dd,9a,a1,7d
So I'm guessing that you know what to do: activate the trial serial (i.e, simply run RMXP/VX with an internet connection). Now go to the registry and export the values.
I'm guessing you must have exported the registry entry like this:
What you need to do is, also export this:
Now, right-click the .reg files you just exported, and click "Edit". It will open in the notepad. Now all you have to do is combine the two registry files. Open the notepad. Edit each of those files and copy-paste the contents into the empty notepad.
When you save the combined notepad text, save it with the extension .reg. Something like:
abcd.reg
file.reg
sdfcsdc.reg
That's it, this file you just created will do the trick.
