Hello,

 

I am only 2 weeks into learning WIX and haven't done much beyond the
installer stuff that comes canned in VS so bear with me. I was confronted
with a challenge at work concerning an upgrade package that is simply
refusing to replace a file. The guy who normally builds it insists he has
taken all the usual steps and due to time constraints I have to take him for
his word.

 

I was able to write a wix component that uninstalls our products with a call
to msiexec in a custom action. This project has no file or directory
components, not even a feature (now that I write this I am wondering if the
lack of a feature is what my problem is). It's a simple dll that makes a
call to msiGetEnumeratedProducts and iterates through each product code
related to a given upgrade code and uninstalls it. When I run this by
itself, it removes the products and all is well.

 

However, we also want to install the new product so I generated a bootstrap
manifest, built that and got my msi, the installer and a new setup.exe which
I imagine wraps the chain that calls each package. When I run the setup.exe
however, it sees the project with custom actions then acts like its running
it and proceeds to the exe but it doesn't actually run. Again when I click
on the msi that is just the custom action that the bootstrap manifest
generated for its output, it runs fine.

 

I've lurked and know you guys will ask for log files however when I try and
run the bootstrappers setup.exe (the chain wrapper) through msiexec I get an
error saying it's not a recognized something or other and won't run and
since that is where the problem exists, im at a loss.

 

Any help would be greatly appreciated

Steve
