I have already tried all the options that you advised me and nothing has functioned
Octanium I am sorry but I am not finding any registered copies of Lightroom under the e-mail address you are using to post to this public forum.
If you have purchased Lightroom then it is possible it may be registered under a different e-mail address. As Kglad indicated in message #3 you will want to be prepared with alternate e-mail addresses or phone numbers that may have been used to register the Lightroom 5. You will want to provide this information to our chat support team at Contact Customer Care .
If you are trying to install Lightroom 5.7.1, as part of your Creative Cloud membership, then please make sure to utilize the Adobe Creative Cloud desktop application to begin the installation process. Details regarding the process can be found at Learn how to download your Adobe Creative Cloud apps .
If your Creative Cloud membership is not being seen on the Windows 7 computer then please see Resolve connection errors with Adobe Creative Cloud and Creative Suite applications for information on how to resolve the connection error.
