After converting a database from Access 97 to Access XP One user is recieving an error missing or broken reference to file DAO2535.tlb. I found the said file DAO2535.tlb on my machine and copied to the user's machine, that fixed the messge and everything compiles. Now I am finding messages that is just really a cover up to the message and that I need to convert and upgrade all the code. Anyone else have this problem. Am I still OK with just copying the DAO file?
