Multiple related installations

[GrandChain]

Hi,

We have a family of products which have the same core components and executables, but different support files. These support files are additive - i.e. if I install product X and product Y I should get the core plus the files specific to X and to Y (with the core being upgraded as necessary if it has moved on between the two installations).

On uninstallation of X I should be left with core + Y (and vice versa).

So two questions:
- is this possible?
- if so, how do I go about it?

Thanks,

Ian

Hi,

Okay, here's what I've come up with.

Our products each have a unique ID which can be expressed as a 6-digit hex number.

I have set up the product GUID as
{77271EBD-#ID_PART1#-#ID_PART2#8E-AF2C-A4088D485549} (I took a generated GUID and picked on 6 digits in the middle).

I pass in ID_PART1=xxxx ID_PART2=xx when I build the kit from the command line (for example ID_PART1=1C23 ID_PART2=1F).
This generates a unique kit for each product.

I have marked the core stuff as shared.

This all seems to work.

Is there any reason I might see problems with this approach?

Thanks,

Ian
