Here is the issue, I have an app called Trent which a colleague has created an MSI for, Application version

There is now an update available from the server which is downloaded via a GUI wizard. I want to capture this update version as a patch to the original MSI so users don’t have to run the wizard. This application is updated every 1/4

I installed the original package then captured the update as an MSI, and then tried to create a patch using Wise Package Studios (v5.2) Patch Creation Tool.
I ran the Upgrade sync tool before hand and it complained about components missing (obviously as the new MSI is not the full install)

After running the Patch Creation tool I had my new MSP file but when trying to run it pops up a message Error Applying Transforms!

Do I need to install the application from scratch using the vendor supplied install, update via the GUI, snapshot to create my MSI then do a Patch?

I have done some patches before but they have been very small changes (Shortcut paths mostly) Am I going around this the wrong way and if so can someone correct me please, patching still seems to be a very grey area!! [&:]

I'm not 100% sure here, but I do belive you can only make a patch between 2 complete MSI files. The patch will then be the difference between the two. So in this case, you have to make an MSI of the new version, and then make a patch between the two.

Also, you should upgrade to WPS 5.6, as an upgrade from version 5.2 to 5.6 is free (any version 5 can upgrade to newest version 5, that is 5.6, for free).

The first MSI and second should be made with WPS or things could get very tricky because different packaging tools use different logic for building setup capture MSIs. The second MSI should be a capture of the original MSI (or vendor install) and the patch going over top of it. Then upgrade sync should then be able to sort out everything. The other alternative is to take a copy of the original MSI and manually update that MSI with the changes you found by setup capturing the patch. Then you should be able to make a patch out of that.

Cheers guys [:)]

I kind of thought that was going to be the case, I was just looking for an easy way out I guess [8|] Problem is the original install document was lost so it looks like I might have to do the cardinal sin and snapshot our MSI![:'(]
