Software Deployment

Ramu,

Try uninstalling previous version by adding custom action sequencing after AppSearch.
Hope it helps.

Manu

Thanks Manu.

In Execute immediate / Execute Defferred context?

Sorry Manu, I just realised that AppSearch is under User Intrface context.

what is the condition I have to use in my CA.

Condition - Not Installed

No Luck..

here is my condition.

If Not Installed then
Run WiseScript Installation .\wisescript.exe
End

In WiseScript.exe, i am just uninstalling the package 'msiexec /x productcode /qn'

pls help to uninstall.

Ramu

Is Product Code also the same?

What is all this nonsense with Custom Actions to uninstall?

An UpgradeCode will be used in conjunction with the FindRelatedProducts action to determine an application's upgradability. If you want to simply uninstall the previous version - not upgrade it - then move the RemoveExistingProducts CA to earlier in the sequence.

Ramu,

no this will not help
what has appsearch got to do with an upgrade

as vbscab has said just move the removeexistingproduct action so it's after installvalidate but before installinitialize

removeexistingproduct action is placed after installvalidate before installfinalise in my transform.

what do i need to do? do i need to create any entry?? can you please little bit in detail to understand.

Thanks~Ramu

small correction:
removeexistingproduct action is placed after installvalidate before installinitialize in my transform.

what do i need to do? Nothing, except do some research.

1. If the product code and package code are same for your earlier and the current versions, upgrade will not happen. You must change these two codes in the current version's MSI (Changing this in MST wont help). I understand this is a VMSI but still I believe there is no other way. And make sure you do this change in MSI only with ORCA. Upgrade codes can be same. That is not a problem.
2. Make sure the upgarde table is properly populated with the upgrade code and the version details.
3. Place the action, RemoveExistingProducts between InstallInitialize and InstallValidate in Execute Immediate.

If you still face issues. check for the following actions in the log and post it here...
RemoveexisitingProducts
FindrelatedProducts

Wait a second, wait a second...I've just re-read your original post.

What you need is neither an upgrade nor an uninstall. What you need is a RE-install:

MSIEXEC /I [path_to_and_name_of_MSI] REINSTALL="ALL" REINSTALLMODE=[your choice, but try "vomus"]

Thanks for the help!!!

I sorted out this problem using a wrapper executable. Here are the steps and i successfully upgraded.
1. In my wise script, first i checked for the existing package with productcode and if it is installed, uninstalled.
2. then installing the new transform with the same old vendor supplied MSI.

Yes..this way i have completed my upgrade and installed new one.
once again thanks everyone for their suggestions.
