;
; This InnoSetup script shows how to install the Visual Basic Runtime files, DCOM and MDAC.
; You should go to the following webpages for dowloading the files and getting the most current information about the components:
; VB Runtime files: How-To Article on http://www.jrsoftware.org/ishowto.phtml?a=vb and http://msdn.microsoft.com/vstudio/
; DCOM: http://www.microsoft.com/com/dcom/dcom95/dcom1_3.asp and http://www.microsoft.com/com/dcom/dcom98/dcom1_3.asp
; MDAC: http://www.microsoft.com/data/
; Recommended release versions (October 2002):
; - Visual Basic 5.0 Sp3
; - Visual Basic 6.0 Sp5
; - DCOM 1.3
; - MDAC 2.5 Sp1/Sp2 (contains ADO 2.5, Microsoft Jet 4.0, OLE DB Providers for SQL-Server 7.0 / MSDE 1.0 and SQL-Server 6.5)

;    -> MDAC 2.5 is the version that comes with Windows 2000 SP1
;    -> MDAC 2.0 and above require DCOM on Windows 95 machines for installing successfully
;    -> There are some issues with existing Microsoft ODBC Driver for Access, version 3.51
; - MDAC 2.6 (contains ADO 2.6, OLE DB Provider for SQL-Server 2000)
;    -> MDAC 2.6 has some issues with SQL 7.0 or SQL 6.5 Clustered Servers
;    -> MDAC 2.6 doesn't contain Microsoft Jet drivers
; - MDAC 2.7 (contains ADO 2.7, same version that is shipped with Windows XP)
;   -> MDAC 2.7 is NOT SUPPORTED on Windows 95
;    -> MDAC 2.7 has some issues with SQL 7.0 or SQL 6.5 Clustered Servers
;    -> MDAC 2.7 doesn't contain Microsoft Jet drivers
;
; Comments:
; It may not be possible to install DCOM95 and MDAC in sequence (without a reboot between them) on Windows 95 systems,
; because Windows 95 comes without any DCOM version.
; Therefore MDAC is installed on Windows 95 systems by a HKCU\...\RunOnce registry entry after reboot, which requires
; that the same user (who executed the setup) logs in after the reboot for successfully installing MDAC.
; (It is not possible to use a HKLM\...\RunOnce entry, because there are timing problems with the after-reboot processes
;  of the DCOM installation.)
; The mdac_typ.exe file stays in the {%TEMP} folder after installation. If you want to prevent this, you should distribute
; mdac_typ.exe as external file and execute it from {src} (for example).
;
; Please remove and set comments in the [Registry] and [Run] sections depending on the distributed MDAC version, but always
; consider carefully which MDAC/ADO version your applications really requires and read the appropriate release manifest before
; distributing MDAC.
