Installing MDAC2.8 redist causes explorer.exe to hang at 100%, and other logon errors

[CChong]

I have recently repackaged and build a MSI for an older installer application named "Headstart Mathematics".

Part of the original installation routine was to install MDAC 2.7, me thinking "newer = better" removed all of the relavent MDAC information using Repackager and added the MDAC 2.8 redist to the package using InstallShield X Editor (along with COM controls and a few other misc OCX redists).

Upon distribution to a clean (windows 2000 sp2 only) test workstation it apears to work perfectly.
Upon distribution to a fully installed workstation after any user logs in it generates the following errors:
Windows Update:
An error occurred calling "DllRegisterServer" in "C:\Program Files\Common Files\System\ADO\msado15.dll". (HRESULT = 80070005)
Then the same, but msador15.dll HRESULT=8002801c
Approximately 5 more errors with different DLLs and different results follow, then explorer.exe will hang at 99% CPU utilization for about 10mins and then continue to desktop and work as normal.

The fully installed workstation has the following software installed:
Acrobat Reader 6.0.1 (Adobe supplied MSI)
Macromedia Flash Player 7.0 (Original MSI)
Office 2000 Pro CD1+2 (Original MSI)
Project 2000 (Original MSI)
QuickTime 6.5 (Custom MSI repackaged from the full download)
Shockwave Player 8.5 (Original MSI)

Have i done something silly/wrong?

I have just tried the same with MDAC 2.7 and get the same results, surely i've done something wrong here?

Another update to my own thread 😮

If i log into the test box as an administrator user, a few post installation routines run and no errors.
I've looked in event log and i've got a whole host of file protection warnings too, i presume thats whats causing the problem.

Does anyone know of a way of using this merge module and deploying the MSI using Active Directory?
