I have an MSI admin install and I need to replace an file in it with a newer version. I don't have a compressed copy of the MSI. How do I go about replacing the file, including any requirements to update version details or package code in the MSI, baring mind that I need this package to repair correctly for existing installations too.

I don't think you need the WSI step if it's an AIP you're working off. Just replace the file in the folder structure and change the pertinent entries in the File table.

You might even get away with a Small Upgrade in this case (only change Package Code). Just run through the checklist here: http://kb.flexerasoftware.com/doc/Helpnet/installshield12helplib/MajorMinorSmall.htm

The first rule of a packager are:

1. Never touch a ventor MSI !!!

Create a MST, that is verry simple and the best way to create no errors or problems

1. Convert the MSI into WSI
2. Delete the file that needs to be replaced.
3. Keep the newer version file at that location and than import it to your WSI.
4. Spin the package code and product code, taking into care not changing the upgrade
code.
5. Accordingly make changes to Upgrade table.
And you are good to go. :)

  • Can I confirm why it's necessary to convert it to a WSI? Is this just best practice?
  • Yes it is considered as best practice but i agree with @pjgeutjens on just changing PackageCode.
  • How about creating a transform .
  • First rule of MSI packaging is to never repackage a vendor's MSI. You void all support and will have problems with future upgrades.

    If this is an "in house" MSI, then modify it however you feel is right, but you could proboably ask the developer to make the change for you and give you an updated MSI. If this is a vendor's MSI, an MST is the best and safest course of action.
    • @Praveen: Yes bro thats how it should be done.
    • @Praveen: Yes bro thats how it should be done.
      • @akki .. I want to tell you it should be done by creating a transform rather than converting MSI to WSI and then editing it .. anyways you corrected it .

        Thanks.
  • @jmaclaurin: You are absolutely correct brother, I dont know how could it possibly escape from my mind. Ty for correcting me. :)

The easiest way is just to replace the file in the folder structure.
Open the msi in for Wise. Change the version number for example to 1.0.0 to 1.0.1
Check the the Wiseversioninfo table. Delete the file you have replaced. Recompile

Creating a transform is the best way to go about this.
