I too am receiving this error on some machines.  I've installed the v12.53 Excel add-in (we use QC 12.21), the Connectivity and VS Runtime.  I tried the certificate fix, to no avail.  The odd part is the error occurs on some machines, but not others.  I've checked the OS and Excel versions in both environments, and they match.  I'll be very interested to see if a fix comes along.

Hello,

 

I'm trying to instal the Excel add-in for HP ALM.

In the Excel_Readme_12_53.htm, you can read (as you copied it as well) : 

    1. Launch the HPCodeSigning.cer file found in the Microsoft Excel Add-in installation folder.

      ... But this file is nowhere to be found...

      Would you have a completre path to give?

      Thanks a lot for your help!
