Windows was unable to install the modem RRS feed

  • Question

  • Attempting to install any modem, I get an error message

    "Windows was unable to install the modem"

     

    Now I know that this problem is documented with service pack two, and it is supposed to be a subkey with deleted entries. All you havet o do is to set them back to normal. The only problem is that the subkey is intact, so this is not the problem. I would imagine, though, that it is something very similar. A different subkey perhaps.

    Anyone help?

  • Mate, did you ever get an answer to this? I have exactly same problem,old PCI modem failed, "Windows cannot install modem" with different manufacturer PCI modem & different again serial external modem. The subkey is intact. What next?

  • Take a look at:
     
    The thread does not mention that modem installation issue, but creating the missing RunOnce
    registry key worked for me.
     
    Good luck!

  • I beleive that the documented fix relates to this:

    REGEDIT4

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Modem]
    "ErrorControl"=dword:00000000
    "Group"="Extended base"
    "Start"=dword:00000003
    "Tag"=dword:00000004
    "Type"=dword:00000001

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Modem\Parameters]

     

    But I also found that the keys were intact.  I checked the RunOnce key mentioned in the link in one of the replies and it was also there.  For giggles I removed the key "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Modem\Enum" and the modem installed fine.  I'm using it as I complete this post.

     

    PS  The computer running Windows 2000 Pro SP4
