I understand that it's crucial to keep your software updated and meet the file space requirements. I'm here to help you fix the error you encountered while installing the update, @Carol.
Error 1635 usually occurs when the update installation package is corrupted or incomplete. QuickBooks requires at least 1 GB of space to run the install process and 2.5 GB to work at its best. You can follow these steps to check how much space you have:
- Click the Windows Start menu.
- Enter File Explorer into the search and open File Explorer.
- Click My Computer from the navigation bar. This is sometimes called This PC.
- Right-click the icon for your hard drive. This is usually Windows (C:).
- Choose Properties. You'll see how much free space you have.
