No Temporary Folder

The operation you requested requires the use of a temporary folder for the storage of intermediate files. WinZip was unable to identify or create a temporary folder using standard Windows techniques, so it is unable to complete the operation.

To locate a temporary folder, WinZip searches for a folder specified by either the TMP or TEMP environment variable. If a folder is not found, WinZip then looks for a TEMP subfolder within the Windows folder; if the TEMP subfolder does not exist, WinZip attempts to create it. You will see this message only if all of these attempts fail.
