Version conflict

[John]

Hi

I have version 1 of an app already installed on client computers. Now I want
to install version 2 of the app while keeping version 1 for now so client
can test version 2 while keep on using version 1 for now. When I try to
install version 2 I get the message "Another version of the product is
installed...". How can I get round this?

Thanks

Regards

[John]

Re: Version conflict

I have now changed the product id of the app and recreated the set-up. This
time it goes past the stage where it gave message last time but now it says
'Unable to install because a newer version of this product is already
installed.' which is strange as I have just compiled this latest version and
it should be the newest.

What am I missing?

Thanks

Regards

Hello, John!

JWhat am I missing?

It seems to me that you have smth wrong in our Upgrade MSI table
( http://msdn.microsoft.com/library/de...rade_table.asp )

Did you changed Package GUID?

What do you use to build your setup package?

Re: Version conflict

I did change the package id after my post and before second post. I am using
vs2003 set-up project to create set-up msi.

Anything I can do from here?

Thanks

Hello, John!

JAnything I can do from here?

Just a hint you can disable flags in setup project properties.
Set to false DetectNewerInst alledVersion

If you want to have more control over install process, then setup project is not
appropriate for you.

As an altrenative you can try using WiX
( http://www.tramontana.co.hu/wix/ )
( http://wix.sourceforge.net )

Re: Version conflict

I am worried that forcefully installing version 2 could effect working of
version 1. How can .net be convinced that version 1 & 2 are completely
different apps and should not be related to each other?

Thanks

Re: Version conflict

You've built a separate setup so that MSI sees both setups as different
products, but it's up to you to make sure that you can run two versions of
the app on the same system. The tricky areas will be items that are shared
or should be unique, such as services, folders used by the running app,
identical assemblies in the GAC, identical shared files in other places.

Re: Version conflict

Any information available somewhere on how to do that? There must be others
in the same situation wanting to deliver more than one app from the same
base code (basically different generations of the same app).

There are no common services or folders in my case though.

Thanks
