The error message with %s\\%s is correct. The first %s should contain "SYSTEM\CurrentControlSet\Control\Network\{4D36E972-E325-11CE-BFC1-08002BE10318}", and the second %s should contain "{016A6C21-3C79-4285-AEC2-A08BB7BB0215}" in your case. The value for second %s was read from enumerated registry "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}\<any number>\NetCfgInstanceId". I can not exactly say, what's wrong here.

Please open registry key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E972-E325-11CE-BFC1-08002bE10318}". This is the list of all network drivers. From this position search for value "tap0801co" (CTRL-F). You will find it for name "ComponentId". In the same level: Please check the value for name "NetCfgInstanceId". There should be value like "{016A6C21-3C79-4285-AEC2-A08BB7BB0215}". Is it?

Yes, empty key with only a "Default" is not normal.

To fix it, please remove and install the driver again.
C:\coLinux\netdriver>tapcontrol.exe remove TAP0801co
C:\coLinux\netdriver>tapcontrol.exe install OemWin2k.inf TAP0801co
