Acrobat X Standard - Post-Installation Serial Number Question

Is there any way to install Acrobat X Standard in such a way where it will wait to prompt for the serial number when it is launched for the first time, instead of upon installation?

I read an earlier post that indicates you can remove the ISX_SERIALNUMBER instance from the ABCPY.INI file to force it into trial mode, but that does not work for this version.

Any help is appreciated.

Thanks!
