Unable to run Microsoft Office 2007 Std. Setup after Signing with Custom Digital Signature RRS feed

  • Question

  • We are Signing Microsoft Office Installation files with our Organizations custom signature. We are using Signcode.exe to Digitally Sign all the exes which are there in Microsoft Office 2007 setup package. But after signing when we are trying to install the software its showing unable to locate the dwtrig20.exe file. When we are signing only setup.exe, at the time of installation its showing unable to find setup.exe. It looks like whichever exe we are signing setup is unable to find that exe. We have checked the setup log its showing setup.exe is corrupted.

    Is there any option to sign microsoft office 2007 with Custom Digital Signatures?

  • Setup looks for particular files based on their filename, and based on the fact that it's signed by a particular key. Specifically one that was generated by Microsoft.

    You cannot sign it yourself.

  • Thanks Steve,

    I got the same reply from Microsoft also. But Office 2003 is working properly. Office 2007 and 2010 is not working after signing.
