We need to know the exact word-for-word error message. We need to know the exact version NUMBER of Windows 10 and bit depth of the operating system. We need to know the exact version NUMBER of Lightroom you are referring to. (Or are you referring to Lightroom Classic? We would still need to know the version NUMBER you want to install)

Within Windows 10 there are specific minimum release versions that add features required by newer versions of Lightroom. In this case it's version 1903 of Win 10. https://support.microsoft.com/en-us/help/4027667/windows-10-update

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Paste that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.
