I have tried downloading Lightroom from my creative cloud multiple times and it will not open on my computer. I have tried logging out and logging back in multiple times as well, but it does not solve the problem. I tried downloading Lightroom from the Adobe website as well, but while that does open on my computer it is "unable to change modules" Is there any way to fix this?
What operating system?
How much RAM?
Is this your first Lightroom installation?
Are there any error messages? If so, what is the exact message?
Did this just started happening?
