Problem
The following error message appears in UVI Portal when attempting to install a Soundbank or a Falcon Expansion via UVI Portal although there is enough free space on the destination disk:
"Cannot install product
Could not install the following product: [ProductName]
(Not enough space for the temporary file [RarFilePath]
required: X GB available: X MB.
If the problem persists, please contact the UVI Support Team"
Solution
When installing a Soundbank or a Falcon Expansion, UVI Portal actually requires temporary space to handle the downloaded file (RAR archive) before extracting then deleting it once the installation is done. Technically, this means that you need enough free space for both the downloaded and the installed file during the installation process.
You can select a different download location (i.e. on a different drive, with enough free space) via the Temporary Download Folder option in UVI Portal's Preferences. Click the Browse button, then select a new location.
