When upgrading Alert Manager, why does it install a new version as opposed to upgrading the current version on the server?

I followed your upgrade instructions to the letter and there are multiple versions installed in Add-Remove Programs. Shouldn't there only be one copy of the software with an update applied? Also the DLL versions in the GAC are 1.0.0.0. Shouldn't they be the same version as the software?

We are thinking that the multiple copies may be causing our daily alerts on spesific (not all) Document Libraries from firing at the delivery time stated. We get confirmations for the alert, just no alert itself.

Please advise,

To find the versions of the assemblies in the GAC, right click on the file and select properties. Then go to the version tab and click Product Version to see the actual build version of the assembly.

 Installing a new version over an existing installation will retract the installed solution and install and deploy the new version so you should not be able to have 2 versions installed within SharePoint at any time. Windows keeps track of each instance installed in the registry but uninstalling from Add/Remove Programs will only remove the registry entries associated with the installation and the Program Files directory if it is the last instance uninstalled. It will NOT uninstall the solution from SharePoint. You will need to use the Configuration Manager or go directly into SharePoint to remove it.

Here are the images from our server:

As you can see, there are 2 instances of Alert Manager installed.

What are your reccomendations? Because this was the result from the upgrade instructions that were provided to me from your web site.

UPDATE: Here are 2 other images of 2 different libraries addalert.aspx page. As you can see one does not give the option of Daily or Weekly alerts.

Sorry to bump this, my company is in the process of purchasing support from you guys, but sort of need an answer on how this happened and if this may be a cause of some of our issues.

The version showing in Add/Remove programs is the version of the installer and most likely shows up multiple times due to the differences in versions of the installer. You can remove the 1.0.0.0 version but leaving both as is will not affect the application.

As far as the alerts not firing properly, here are a few things to look at.

In Central Administration go to Timer Job Definitions on the Operations tab and make sure there it an Immediate Alerts on each of the web applications you have alerts set on and make sure they are not Disabled.

Also, create an alert using the basic SharePoint Alert Me alerts to see if these fire successfully. If so, then create the same alert using Alert Manager's Advanced Alert Me without using a custom alert template and see if these are successful. Immediately after creating these alerts, reset the Windows SharePoint Services Timer service.

If after checking all of these, contact us at softwaresupport@sharepointsolutions.com for further troubleshooting.
