InstallAware

I have three versions of an application that need to be installed side-by-side: 1.0, 2.0, 3.0. I've (sequentially) given them unique Product IDs and Installation directories (as well as shortcut names). I can successfully install the applications sequentially: 1.0, then 2.0, then 3.0; but if I try to install them out of order, I get a user-privileges error telling me to run the installation as the administrator...which results in the same error.

The application directories (for all intensive purposes) are:
C:\Program Files (x86)\Company\Application
C:\Program Files (x86)\Company\Application 2.0
C:\Program Files (x86)\Company\Application 3.0

I tried to change the directory, but to no avail.

What's going on with this Product ID and or revision checking that I should know about? I find it very strange that I can install them sequentially, but not out of order.

Hi,

You might want to look at using Transform Instance. It is a Windows Installer MSIcode command that allows you to have multiple version of one setup installed.

Shouldn't a unique Product Code differentiate these applications (versions)?

I opened the .mpr file as text to see how changing the Product Code affects the file. As it turns out, there's another (non-specified) Product Code under the Product Code I expected. What generates this product code? How can I change it (without manually manipulating the .mpr text)?

Also, I tried "Transform Instance", but to no avail...I still get unexpected errors when installing the older version "Application 1.0" next to the new version "Application 2.0".

Hi,

Could you please attach that project here?
