May i know which version of the Lightroom have you installed on the new computer.
Looks like it's for Lightroom CC. Is there another download link I can follow for my version? Maybe I am just using the wrong one.
Sure, please download the Lightroom 3 from the below mentioned Link.
Please note before installing the Lightroom 3 i would recommend you to remove Lightroom CC and Creative Cloud Application if installed from the computer.
