I developed Excel addin. I want to deploy addin it through ClickOnce. Addin publish to a Shared folder. Addin is developed successfully and appears in Excel. but when I change something in Adin and publish an updated version when you start Excel the following error:

The customization cannot be installed because another version is currently installed and cannot be upgraded from this location. To install this version of the customization, first use Add or Remove Programs to uninstall this program: PricelistExcelAddIn. Then install the new customization from the following location: file:///C:/Users/sribin/Documents/Visual Studio 2008/Projects/PricelistExcelAddIn/PricelistExcelAddIn/bin/Debug/PricelistExcelAddIn.vsto

The installation URL of a ClickOnce deployment is a major piece of the identity. You can't install a C/O app from two different locations, and you can't install it from a location that doesn't match the installation URL in the deployment. Having said that, what is your installation URL for your VSTO addin? Surely it's not "c:/users/sribin/documents/visual studio 2008/projects..."

Create a file share somewhere, even if it's on your own machine for testing, and use that as your installation URL, and put the files there.
