Waves Central verifies whether you have sufficient storage available on your system hard drive before the installation begins. If another process is happening during the installation (for example, if you’re downloading, copying, or installing another program in parallel) you may run out of space and this message will appear.
The minimum space requirements for Waves products are:
- Plugins, bundles, live applications and drivers: 4GB available the system drive.
- Waves Creative Access: 15GB available on the system drive.
- Waves sample libraries (for virtual instruments and COSMOS) may require more available space. The exact amount depends on the product and is calculated before installing. Note that sample libraries can be installed on any drive you wish. To change the default sample library folder, access Waves Central’s Settings tab, then press Change next to ‘Sample libraries data folder'.
Waves Central will not allow you to install if there is not enough storage space on the main system hard drive. The Install button will be grayed out and the required storage space will be displayed. Clear the required space, quit or pause any application or process that could be downloading, copying, or installing while Waves Central is installing, refresh Waves Central and try installing again.
You can also clear some space by:
1. Clearing Central’s cache: Access Waves Central’s Settings tab tab, then press Clear next to ‘Clear Central cache’.
2. If Waves sample libraries are installed on your system hard drive, move them to a different drive. Learn how.
