256986 Description of the Microsoft Windows registry



SYMPTOMS
When you click Add on the Driver tab in the Tape Devices tool in Control Panel, nothing may happen.



CAUSE
This issue can occur if registry values that are used to display the Install Driver dialog box are missing from the registry.



RESOLUTION
Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To resolve this issue, use a .reg file to re-create the appropriate entries:  Create a file with the following contents:

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{6D807884-7D21-11CF-801C-08002BE10318}]

@=&quot;Tape drives&quot;

&quot;Class&quot;=&quot;TapeDrive&quot;

&quot;Icon&quot;=&quot;1610&quot;

&quot;Installer32&quot;=&quot;SysSetup.Dll,TapeClassInstaller&quot;

&quot;LegacyInfOption&quot;=&quot;TAPE&quot;

 Save the file with a .reg file name extension. 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.
