Windows was unable to install the modem

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?

Take a look at:The thread does not mention that modem installation issue, but creating the missing RunOnceregistry key worked for me.Good luck!Regards.Wednesday, March 21, 2007 11:15 PM

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.
