 * Microsoft Plus! for Windows 95

SYMPTOMS
When you try to install Microsoft Plus! for Windows 95 using a 3.5-inch standard (non-DMF) 1.44-MB disk set, you may receive the following error message when Setup reaches eight percent complete:

The compressed file ' :\plus_1.CAB' cannot be decompressed and may be corrupted.

After Setup closes and you restart the computer, you may receive the following error message when you try to perform a DriveSpace operation:

The compression driver that is currently loaded is incompatible with your version of Windows compression. ID Number: DRVSPACE484

In addition, you may receive "Out of memory" error messages if your Windows swap file is located on a compressed drive, and the Disk Compression status line on the Performance tab in System properties may report that compressed drives are being access in MS-DOS Compatibility mode.

CAUSE
The cabinet (.cab) file located on disk 1 is damaged. The disk sets known to have this problem have a disk assembly number of 320-051-013. The disk assembly number is located in the lower right corner of the disk, above the words "All rights reserved."

The damaged cabinet file prevents Setup from copying the protected-mode DriveSpace 3 driver (Drvspacx.vxd) to the hard disk, and causes Setup to fail. When you restart your computer, the real-mode DriveSpace 3 driver is loaded, causing your compressed drives to use MS-DOS Compatibility mode. This driver is incompatible with the Windows 95 version of DriveSpace that is currently installed, preventing you from running DriveSpace in Windows 95.

RESOLUTION
Remove the Program Files\Plus! folder that was created by Setup, and then reinstall Microsoft Plus from a CD-ROM, a 3.5-inch DMF disk set, or a 3.5- inch standard (non-DMF) disk set that does not have this problem. To obtain a replacement non-DMF disk set that does not have this problem, please contact Microsoft Product Support.

If you are using DriveSpace and you cannot reinstall Microsoft Plus! from a CD-ROM, a 3.5-inch DMF disk set, or a 3.5-inch standard (non-DMF) disk set that does not have this problem right away, restore the Windows 95 DriveSpace files that were replaced by Microsoft Plus! Setup before you use Windows 95. To do so, start your computer at a command prompt, change to the drive containing Windows 95, and type the following commands. Press ENTER after each command.

NOTE: These commands assume that your Windows folder is named Windows. If your Windows folder is named something else, substitute the name of your Windows folder in the following commands.

  cd \windows\command copy drvbin.w95 drvspace.bin /y copy dblbin.w95 dblspace.bin /y copy drvsys.w95 drvspace.sys /y copy dblsys.w95 dblspace.sys /y cd \windows\system\iosubsys copy drvvxd.w95 drvspacx.vxd /y cd\ attrib *.w95 -s -h -r attrib *.bin -s -h -r copy drvbin.w95 drvspace.bin /y copy dblbin.w95 dblspace.bin /y NOTE: Depending on the version of MS-DOS or Windows that was originally used to compress your drive, some of the .w95 files referenced in the above commands may not exist. If you receive a "File not found" error message after typing one of the above commands, try typing the command again to see if you typed it correctly. If you receive the same error message again, move on to the next command.

If the drive that contains the Windows folder is not also the physical boot drive, change to the physical boot drive and type the following commands. Press ENTER after each command:

  cd\ attrib *.w95 -s -h -r attrib *.bin -s -h -r copy drvbin.w95 drvspace.bin /y copy dblbin.w95 dblspace.bin /y After you type these commands, restart your computer.
