Resolve the error when upgrading Spectrum: "There is not enough space on the disk"

Products affected: Spectrum™ Technology Platform
 
To resolve this issue for an upgrade, the disk where the temp folder is located must have 10 GB of free space plus four times the size of your current installation. For example, if your current installation is 5 GB, you would need 30 GB of temp space: (4 x 5 GB) + 10 GB = 30 GB. If necessary, modify your TEMP environment variable (Windows) or IATEMPDIR environment variable (Unix and Linux) to point to a location with enough space.

If adding modules as part of the upgrade, users will need 3 GB to install all modules, (less if installing fewer modules).

For a new installation, the disk where the temp folder is located must have at least 10 GB of free space for the installation to extract the files it needs. You may need more depending on the options you are installing. If necessary, modify your TEMP environment variable (Windows) or IATEMPDIR environment variable (Unix and Linux) to point to a location with enough space.

Note: If installing a module that uses a reference database, such as a postal database, geocoding database, or data normalization tables, space will be needed for this data. The total disk space varies, depending on what modules(s) and what database(s) are being installed.
