Error installing .pkg

Hey there,

I'm currently rolling a new software out (to a few hundred endpoints) with JAMF pro.

I do it with a policy that installs the .pkg and the scope is every user that has not installed it yet.
It does work for all the endpoints except about 10. These 10 endpoints get the following error:

Executing Policy program name Verifying package integrity... Installing program.pkg... Installation failed. The installer reported: installer: Package name is Program installer: Upgrading at base path / installer: The upgrade failed (The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assistance.)

I looked at some existing threads but no solution helped me. I also tried to cache the pkg first and install it with a second policy.

Does anyone know what to do?

I found the problem already.

It seems like the first time the program was installed, it worked fine but JAMF didn't find the program on the endpoint. That means JAMF didn't exclude it from the smart group and tried to install it on top of the existing installation which caused the error.
To fix that I just manually uninstalled said program from the endpoints and JAMF did its thing.

It was no adobe product but an anti virus system.

What are you installing? Is it an Adobe product?

I see this when the user already has the version installed. Does this package have a post-install script to check the version?

I'd check the install logs on those 10 endpoints to see what you got.

@leonwun Drop the installer pkg into Suspicious Package to see what the preinstall or postinstall scripts are doing. It could be checking for an existing install, or an OS version compatibility check is failing.
