General Description: This answer record contains information on the Readme file for 2.1i Service Pack 6 for PC platforms.
This 2.1i Service Pack 6 Update is intended as an update to all 2.1i Alliance and Foundation installations on Windows 95/Windows 98/Windows NT machines.
All fixes packaged in the previous 2.1i Service Packs are included in Service Pack 6. Installation of the earlier Service Packs is NOT necessary.
Service Pack 6 requires AT LEAST 200 MB free disk space to complete installation. If fewer than 200 MB of free TEMP disk space are available, the following error may be reported: "PackageForTheWeb Error: System error during decompression." Creating extra disk space will allow the installation to successfully complete.
NOTE 1: The destination directory specified during the setup operation must contain an existing 2.1i installation. Only existing files will be updated. Any new device support not previously installed should first be installed from the 2.1i CD before the Service Pack update is added.
NOTE 2: Foundation users must perform the setup operation on a machine with an existing Foundation 2.1i environment.
