Is it possible to see what release a particular user is running on their device(s).
For example user joesmith#myapp.com is running my app. He claims to be running version 2 but the behavior in the app makes me think that he is running version 1.1.
Is there a way to look up that user in fabric.io (assuming that we are calling setUserIdentifier) and seeing ALL the versions that user is running?

I was thinking of this today and was wondering what is it on MacOS app that prevent me from running, for example, 5 instances of a specific app?
I was thinking it could be the bundle_id (similar to iOS) but when I copied and renamed the app (to appname_2) edited the bundle_id (to bundle_id_2) for that specific app it didn't launch and instead just put that application in the foreground.
Maybe there's a method that checks the Mac address of the device and only allows one app to run per Mac address.
Due to it being hard to find and info on this online, wondering if it's possible to run multiple versions of an app on my Mac.
I'm pretty sure a virtual machine would work but if I wanted to run 100 instances of that specific app then id run all out of ram and would render my Mac useless for actual work.
The LaunchServices (Finder, NSWorkspace APIs, etc.) on MacOS allow you run one app per user session. Nothing prevents you from launching an app a second time when you don't use Launch Services. (And your assumption is correct that LaunchServices looks at the BundleID to see if the app is already running).
e.g. when you open two Terminal windows and start Mail via (/Applications/Mail.app/Contents/MacOS/Mail) in both you have two Mail instances. open /Applications/Mail.app/ won't work two times because it'll use LaunchServices.
We have a windows service that gets installed and runs on users system in the background, but on some windows machine user get an error "A device or program has requested your attention" This is specific to Windows 7.
This is because when we are installing the .exe on the user machine using MSI(created with WIX), the installer job I believe runs on Session 0, and when any prompt appears the user is prompted that a program has requested attention and he gets switched to Session 0. Can we suppress messages for installer or exe running in Session 0.
Thanks.
To fix this you will have to determine what UI is shown if the user switches to Session 0, what shows it, and how to remove it.
Services run on Session 0. Before Windows Vista, they could interact with the desktop, so many did. Chances are your service is trying to show some UI. Upon detecting this, Windows is trying to help you out. Fix the service to avoid showing UI, and the message will go away.
It's plausible that this could also occur for a deferred custom action in the system context (as those are invoked by the Windows Installer service), but I've never run into this scenario. If so, the fix is the same: make that action not show any UI.
Michael's correct, but I want to expand on it a little.
The issue isn't primarily about session 0 or services. It is about anything that tries to show a UI that is not part of the interactive user's current session. The main problem is the shatter attack where (for example) something running with the system (or otherwise privileged) account shows UI to the (perhaps limited) interactive user. The window into the privileged process is a security hole. As a result, attempts by an install to run custom actions with the system account (deferred CAs) that show UI are an issue, as are services. Session 0 is really just part of the implementation that is intended to address the security issues.
So yes, address UI attempts from your services and from (primarily deferred) custom actions in the install.
I have two different users on my professionnal laptop, one for work, the other for personnal use.
I have a meteor project that I can run without problem with my work user. But when I try running it with my personnal user, I get this error :
This project uses Meteor 1.2.1, which isn't available on Windows. To work with this app on
all supported platforms, use meteor update --release METEOR#1.2.1 to pin this app to the
newest Windows-compatible release.
I read about such problem when trying to run on different OS, but nothing with two users on the same system.
I finally get the solution.
My work user is a domain user and I installed Meteor with this one. I just uninstalled Meteor and reinstalled it with my personal user and it worked fine now.
Thank you in advance for considering this question. If a similar question existed, I was unable to find it.
The Issue: Our company packages an application into an MSI. This MSI when installed outside of any GPO properly updates, blocks attempts to downgrade (or move from a higher revision to a lower revision), and never has trouble uninstalling previous versions of the application regardless of how long ago those versions were created/installed. For example, we can install version 1.2.3 and then install version 2.3.4 and the application will properly install without issue. However, we work with a customer who uses GPO to deploy our application to hundreds of PC's. Each time we have provided an updated version of the application the following has been indicated:
On any machine where a previous version of our application was installed via GPO, no matter what the previous version is, the update successfully installs without issue.
On a machine where the application was manually installed (outside of the GPO), and an attempt to update the application via GPO is made - either the application is installed in addition to the old version, OR there remain registry keys to the previous version of the application and the application cannot open/run correctly. In this case the registry keys must be manually removed, and the install is then attempted again from a clean machine.
What we know is that on any machine where the application was originally installed via GPO - updating the application is no problem. On every machine where the application was not installed with the GPO in the first place, updating via GPO fails with one of the problems presented above.
My question is: Is there a technical issue with how the installation is being handled partially through the GPO and partially outside? Does the GPO need to be responsible for the entire life-cycle of the application? OR is it a reasonable expectation that the application be updated both on machines where the original version was manually (outside the GPO ) installed, and when it was installed initially from within the GPO?
One solution we are aware of is simply having all computers manage the application life-cycle (since we know updates work in that environment already), however this would mean that many computers would need to have the manually installed versions removed by hand - and then properly handle the installation through GPO which is an extensive bit of work.
We would greatly welcome any solutions, references to technical documentation that formally shed light on the proper management or expectations here, or links to information. Our research suggests that it is "best" to manage the entire applications life-cycle inside the GPO - but I have as of yet been unable to determine that it is 100% necessary to do so.
Looking forward to any assistance. If any further technical details are required to help the viability of the question, please don't hesitate to request such details.
If you end up with two versions installed in Control Panel, then all other things being correct, the most likely explanation is that you upgraded a per user install with a per machine install (or vice versa). In the GPO world that's related to assigning it to a user or to the computer, something like that. That's easy to verify by getting a verbose log and checking the FindRelatedProducts actions for an indication that another product was found but in a different context.
When you're in GPO mode all the time, I assume each one (whether it's per user or per machine) is consistent, therefore upgrades always work, but they don't work cross-context.
I believe GPO suppresses the UI in most cases, and the UI (or the UI sequence) is sometimes where per user/per machine is set. That might be something else that would cause it, depending on how the GPO publishes to the computer or the user.
I am working on a developer library that I want to release later this year and it should work under different user rights and also on different windows platforms. The library can be executed in both a web, windows-service and desktop-app-client context.
What combinations of users should I test the application under? Is it enough to test it using
Normal standard user
Administrator
Local system account
Are there any more permutations of users? What kind of typical users/policies do exists out in the enterprises?
Are there any guides about how to Windows "test" software before release so that the number of security/rights gotchas/issues can be addressed before the application hit the customers?
