Replace old exe files with new installer

[Munna232]

Hello all,

I need small help. Please help me.

I created one Installer with LabVIEW’2014 & deployed in other PC.
Now, I want to deploy new applications. but, when I’m deploying new application, still old exe files are exists in installation directory.
I want to replace old files with new exe (without un-installing old installer).
 
For Example: 
Exe V_1.1 is deployed. now, I updated version with Exe V_1.2.  when I'm installing new Installer with Exe V_1.2, still Exe V_1.1 file are exists in same directory.
 
I found some information related to this on below mentioned link. But, I need Upgrade code & product version number for the same.
I don't know product code of my older installer. could you please tell me where can I get this?

As long as the Upgrade Code is the same, the old EXE should be removed.  The Upgrade Code is found in the Version Information section of the Installer Properties.

Dear Crossrulz,

Thanks for your reply.

Actually I dont know upgarde code of my old installer & I don't have old installer project file. I have only setup files (installer).

Is there there is any option check upgrade code without project file (i.e. without Installer properties)?

That upgrade code is a GUID that can be found in the Windows registry somewhere.  It lets Windows know that an installer you have is of the same product, and should remove the old one before installing the new one.  If you can find that GUID in the registry you can set your new installer to it, and it should work.

the upgrade code is somewhere in the registry, but if you have the installer package, you can look it up directly from the msi file with msi editor/info tools, like InstEd, Orca, InstallShield or smething similar tool (athough I've never tried it before but it seems to be working based on various sources)

you should look at the upgrade table 

if you don't have an msi file, you can grab it from the installer exe file, while you start it, it will be extracted to the temp folder (you just have to keep the setup open, until you copy the msi somewhere, then you can cancel it)

edit: that is another approach based on the registry, although I'm not sure if it works: https://groups.google.com/forum/#!topic/microsoft.public.platformsdk.msi/tWBAB5tHbbs

It’s showing more than 100 msi files in Installer package. Could please tell me is there is any specific name of this msi file?

[Munna232]

Dear All,

Thanks for your help.

Finally I got GUID in installation package. This registry file exists in Volume\bin\dp (File name: install.msi).

I opened this msi file with notepad & I found this code.

Hello all,

Can anyone tell me where these all registry codes will be present in PC after installation?

My only suggestion is to open Regedit and do a search on that GUID.  I'm assuming it would be under local machine then software.

[Munna232]

I don't have admin rights to open "Regedit".

Is there is any other way?
