Not sure if this post will relate, but look at the suggestions in this link:

Check a couple of things:

1 - make sure the upgrade code is the same for each version
2 - make sure the product code is different for the new version
3 - try changing the higher number on the assembly, ie instead of, 1.0.x, as you did in the installer.

The lease significant (4th) is ignored most of the time.

Hello Snarf0001,

does not matter if you increase build number of revision number .. it results same.

To get it working, it needs following changes.

1- increase the assembly version by one (does not matter what digit you increase major, minor, build or revision number)
2- Increase the file version (same as in 1)
3- Increase version in installer project (deployment project)

if any of these is same as was in last installed version then it would not overwrite the existing files

Thanks for your replies...
