Hi,
I am trying to build a simple UI installer for our application. I want
to make sure that the application is upgradable in future. In order to
do so, I am playing around with Upgrade element in WIX source file.
Upgrade seems to work fine but I am not able to detect the old version
and newer version and stop the upgrade. Here is what I am trying to do:
1. Install version 1.0.0 of the application.
msiexec /I ClientSetup.msi
Should work fine.
2. Upgrade to version 1.0.1.
msiexec /I ClientSetup.msi REINSTALL=ALL REINSTALLMODE=vamus
Should work fine.
3. Try upgrading back to version 1.0.0.
msiexec /I ClientSetup.msi REINSTALL=ALL REINSTALLMODE=vamus
Should display a message stating that a newer version already exists.
4. Try upgrading back to version 1.0.1
msiexec /I ClientSetup.msi REINSTALL=ALL REINSTALLMODE=vamus
Should display a message stating that this version already exists.
I have attached the source code in a zipped file. Please rename
ClientSetup._zip to ClientSetup.zip. The only change I am doing between
version 1.0.0 and version 1.0.1 is the change on line 7 in Product.wxs.
Please have a look and let me know what Am I missing here? Any help
would be greatly appreciated.
Thanks & regards,
-Sonar
