My file is a 2000 Access database. I have MS Windows XP
Professional, uses Access 2002. My switchboard will open on all other computers in the company, but when I open it on my manager's (of course) I get an error 48, in loading DLL tht opens a MS Visual Basic window.

I tried looking this up on Google and got a KnowledgeBase article telling me to do some Run commands, but this did not solve the problem. I redownloaded MDAC, and used the:
Regsvr32.exe C:\Program Files\Common Files\Microsoft Shared\DAO\Dao360.dll

Regsvr32.exe C:\Program Files\Common Files\system\ado\Msado15.dll

From Article:

The problem is that when I try to register the DLL files, I get the following error:
Load library("C:\Program") failed. Specified module does not exist.

I can go into Explorer and find both of these files in their said destinations. Driving me crazy
