Which application are you using?
How much available hard disk space to you have?
Please ensure your computer meets or exceeds the minimum system requirements to run Creative Cloud + OS + all other apps you use. Check each one. Requirements vary by product. You may need extra disk space and RAM for video and graphics apps that consume a lot of memory. - https://helpx.adobe.com/creative-cloud/system-requirements.html
