Hi -
I rogibally purchased the full version of Lightroom 3. A few months later when Lightroom 4 came out, I purchased the upgrade version of the Lightroom 4. Everything went well with the installation process.
Recently, I purchased a new laptop. I am trying to install LR4 on my new laptop. For this, I first started by installing LR3 and then proceeded to install LR4. LR3 has been installed and works just fine. But upon installing LR4, and clicking on the icon, it brings up the screen where it asks the user to input the serial number of the product.
As far as I understand, the LR4 should detect that I already have LR3 installed in the new laptop and therefore should directly upgrade without needing a serial number. When I tried to put in the serial number of LR3 on that screen, it is rejected by a RED X mark. I did not have such issues to upgrade on my old laptop. Just as an FYI, I am running Windows 8 on my new laptop. Please help!
