How to create a MSI for updating a single file without changing product code etc

[ajitmittal]

I tried it to make msi but it says that "Another version is already
installed, installtion cannot proceed, to configure or modify use
ADD/Remove"


I just need to update one file and need to do following steps:
1. Get the location where software is installed
2. If not installed then prompt for failure
3. If installed then update one file at the location found at step 1
4. After updating inform user about success message.

I don't want to change the product code and don't need upgrade code
Thanks

I think your best approach would be to create a patch for your product otherwise your users are going to have repair issues later on.

Use IS “Quick Patch Project”.

You can achieve this with Quick Patch.

original project was made using InstallScript Project.

Now the idea is to use msi for deploying through Active directory for updating a single file.

For using Quick patch I must be having previous project in msi or quickPatch.

Thanks

You need .msi to do this; Quick patch requires .msi of previous Parent/Base installer. It uses the previous released msi as base, and it gives option to add new file or update the old one.
