I am currently creating a VSTO addin for powerpoint. I am using Visual Studio 2008 development framework for the same. When I try to install the VSTO on my machine, it gives me 'unknown publisher' error. To handle this issue I tried out the following:
- Signing the manifest as well as the vsto with clickonce tool which is inbuilt in powerpoint addin project of Visual Studio 2008 with authentic certificate
- Signing the dlls as well with the same.
Despite this, I get an 'Unknown Publisher' pop up while installing VSTO. Then I installed the certificate on my machine and the 'Unknown Publisher' error never occured. But on other machines where certificate is not installed it gives the same error. So I tried another approach wherein I sign the vsto and dlls and manifest explicitly by Mage.exe. However, it gave the same error while installing on other machine. Please note that the certificate that I use for signing is verified from certificate authority
Please could anyone tell me how to handle this issue.
