Muse and Lightroom show as installed. But they, in fact, are not.
This likely stems from the way I initially set things up. I was using my traditional licensed software but have now signed up with the cloud account. Muse and LR installed but everything had to be uninstalled due to constant crashing. So I took everything off, thought I scurbbed my machine clean of all things adobe.
Now on reinstall, these two programs show as being installed but they are not. Other programs are installing fine and working well.
Thanks for help in clearing this up.
By the way, I'm on a Mac OS. 10.7.5 on a mid 2010 MBP
Thank you. while this did not directly help the situation, I did stumble upon the solution.
In the Applications/utilities/adobe installers folder there were the "uninstallers" for each application that is recognized by the application manager. I ran these uninstallers and it worked, even though for Lightroom it showed only having about 4KB of information to delete. Regardless, it cleared the problem and all is now stable.
