Upgrade not installing old - installing side by side

[don_ucw]

I our project I have the upgrade options set to:
- Automatically upgrade older product versions
- uninstall old version first...
version number is set to 1.0.0

This is checked into TFS.

We use a build server. The AIP is fetched from TFS. The build server command line edits AIP and sets the build number to be (much) greater than 1.0.0.
It does a second edit the AIP for output location. It then loads path variables and performs a rebuild.

I checked the AIP on the build server and the version number is properly set, and the upgrade properties set above.

Suggestions?

thanks

I should describe what happens.

I run a build, it creates build 9.0.0.9000 MSI. I download and install in.

I run a second build. it creates build 9.0.0.9001 MSI. I download and install it.

Both versins are installed.

I would expect that when I run the 9001 build MSI, it would say somelike like "do you want to remove the older version" or automatically remove the old version, based on the sections I made.

Hi,

Please read the "Uninstall existing version and install latest version" thread which debates the same problem.

Thanks for the tip.

FWIW the issue was that MS Installer does not recognize the last number in the build, e.g. major.minor.version.build

I changed the build number to increment on the 3rd number and it now uninstalls the old and installs the new. (e.g. 99.0.1.0 now goes to 99.0.2.0)

You're welcome. I'm glad you got this working.
