To resolve this issue, use a .reg file to re-create the appropriate entries: 1. Create a file with the following contents: REGEDIT4 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6D807884-7D21-11CF-801C-08002BE10318}] @="Tape drives" "Class"="TapeDrive" "Icon"="1610" "Installer32"="SysSetup.Dll,TapeClassInstaller" "LegacyInfOption"="TAPE" 2. Save the file with a .reg file name extension. 3. Double-click the .reg file to merge its contents into the registry on your computer. You do not need to reboot your computer after you merge the .reg file into the registry.
