Windows Installer - Can't install - another version exists

Post by Norm » Mon, 18 Jun 2001 02:43:46



I have a customer who has installed my program which uses the windows
installer.  He got a virus and not when he tries to install Talking Caller
ID he gets this error message:

"ANOTHER VERSION OF THIS PRODUCT ALREADY INSTALLED.
INSTALLATION OF THIS VERSION CANNOT CONTINUE.
TO CONFIGURE OR REMOVE THE EXISTING VERSION OF THIS PRODUCT, USE
ADD/REMOVE PROGRAMS OF THE CONTROL PANEL"

However, it no longer shows up in the list to remove.  He has also tried
removing all references to the program from the registry with no success.

How can he resolve this problem.

1. You can't install MDAC_TYP.EXE using Windows Installer

I have been trying to develop a Windows Installer installation that would
install
MDAC_TYP.EXE using a CustomAction as part of my product install.

I created the basic MSI file to install my application using Visual Studio
Installer.
I then used ORCA to edit that MSI file an add a CustomAction to run
MDAC_TYP.EXE.

When I execute this installation, I get an error message saying "Command
line option
syntax error". So, I tried it with no command line switches at all and got
the same
error message.

So, I contacted a Product Support Specialist at Microsoft. He said that it
can't be done.
And Microsoft knows that it can't be done. Exactly why I'm getting the error
message
is not important. It won't work anyway.

There is a need for the Microsoft DAC development group to develop a Windows
Installer for MDAC, and it hasn't been done.

If anyone knows anything else about this, I am eager to hear it.
