dotnet setup : Install on top of old client version issues?

Has anyone seen weird issues when installing custom clients on top of old
version?

Seen it a few times, remove all versions an reinstall the current again and
it works fine.
This a fairly complex remoting n-tier application, was installed with a MSI
package, other clients work fine when I see the issue.

Maybe i'm missing something, or doing something wrong?

Thanks,

Schneider

What does "installing custom clients on top of an old version" mean? If you
install something with an MSI package and then start changing the files
manually you risk a repair kicking in and restoring the files you replaced.

Case 1:
Install Client 1.0 [with MSI]
Install Client 2.0 [with MSI]

Case 2:
Install Client 1.0 [with MSI]
Remove Client 1.0 [Add Remove Programs]
Install Client 2.0 [with MSI]

Sometimes with Case 1, I get strange issues, usually on some strange
machine. If I remove all the installs and only install the latest it works.
Case 2, always seems to work, just requires an extra step.


Thanks,

Installing on top of another in your case 1 will cause trouble. At least
there's a lot of potential for it. You should really be using
RemovePreviousVersion to automatically uninstall the older version, that's
what VS setup projects support.
