Run-time error 3170.

When using access, a user gets the error message above (couldn't find installable ISAM). I have found documentaion with suggestions to fix this problem but none of them work. I have no more answers for this problem. The system had Office 2000 that was uninstalled and then office 97 was installed on it. It is working fine with another user and I don't know what the difference is. I have uninstalled/reinstalled, renamed dll files, but to no avail. Please send me a small miracle!
