Don't know if I can help but here's a few ideas Have you tried installing Access before/after? Compare the files it installs with your versions. Do a registry compare. Try using Installsheild to create an install set (not the Dlephi version - the full one). Failing that, I have a friend (just 1) that uses DAO in his commercial VC++ product and he has had some joy/unjoy with DAO. I'll ask him for you.

I have an setup which I wrote to install my program and DAO. All was fine on a few machines we tested it on. We then installed Windows 95 and tried our install. We found a problem with our program which caused access violations. We tracked it down to a database problem, one I can not work out... If we run a query using TITAN for access it works fine. But if we add a WHERE clause to the SQL query it causes an access violation every time. Remove the where and it is fine. So we have an database that can not handle a SQL where statement. If I then add MDAC 2 it works, but I also have to add DCOM95. So we thought we would try another install of win95. This time DCOM and MDAC and not out DAO install from our setup. The same thing happens, but now if I run my setup with the DAO installation it works. I can not work this out..... I really do not want to have to install DCOM and MDAC as well as my DAO install. The files I have for the DAO install in my setup are. N:\dao2535.tlb N:\dao350.dll 3.51.1608.0 N:\DAO350.SFP N:\msexch35.dll 3.51.0623.0 N:\MSEXCL35.DLL 3.51.0623.2 N:\msjet35.dll 3.51.2026.0 N:\msjint35.dll 3.51.0623.0 N:\msjter35.dll 3.51.0623.0 N:\msltus35.dll 3.51.0623.0 N:\mspdox35.dll 3.51.0623.0 N:\msrd2x35.dll 3.51.0623.0 N:\msrepl35.dll 3.51.2010.0 N:\MSTEXT35.DLL 3.51.0623.0 N:\MSVCRT40.DLL 4.10.6038 N:\MSXBSE35.DLL 3.51.0623.0 N:\MSRDO20.DLL 6.00.8169 N:\rdocurs.dll 6.00.8169 N:\EXPSRV.DLL 6.0.8246 N:\vbajet32.dll 6.1.8167 N:\vbar332.dll 3.0.6908 Any ideas?
