Software Deployment

there are 2 ways which i am going to try now,
1-
chaining uninstall program before main installation.

2-
putting uninstall custom action in user interface.

Unfortunately for both apps vendor has not set any upgrade code.



how can your msi not have an upgrade code ???

all you need to do is use the upgrade table


enter upgradecode of your first msi


upgradecode versionmin versionmax language attribute remove actionproperty


enter code of previous package xxx xxxx 1033(if english) 773(maybe depends want you want) leave blank entername(uppercase)



make sure the action property exists in the securecustomproperties in the property table


thats all you need

That is the strange thing. Vendor has not set any upgrade code.

Finally I got the solution, if I want to do it through msi.

I put custom action to uninstall previous version, in user interface, and triggered installation with /qr mode.

Still if there is any better way please suggest.

Still if there is any better way please suggest.You mean like cygan did in post # 3?

No. I had to put custom action in userinterface.(Type-98) This custom action uninstalls previous msi, with help of it's product code & as I used /qr, user interface dialogue boxes will come but there will be no any user interaction.

Can anyone guide?

or Can I write 2 line vbscript, which installs msi with /qr switch? will it work through group policy? I

just want to know thoughts, anyways I will ask my deployment guy to test.

You should know by now that it is poor form - in ANY forum - to cross-post.You then compound the error by hijacking someone else's thread. Then you compound THAT by changing the subject!

Please: have some respect.

IT WAS NOT A CROSS POST. IT WAS RELATED TO DEPLOYMENT, SO IT WAS IN DIFFERENT FORUM.
