I have received a workbook with macros in it. I trust the sender and the
workbook is signed with a digital signature. However, I receive a security
alert informing me that the macros have been disabled because the signature
is invalid and cannot be trusted because the issue of the certificate cannot
be found. Despite installing the certificate and adding the document to my
trusted folders, I cannot run the macros in this workbook.

Any inpout would be greatly appreciated.

Check you Macro security setting Tools Macro Security

Try setting them to a lesser level.

That is of course obvious but it degrades my security significatly when I
only want to be able to get this single workbook to work. I want to be able
to selectively override the mechanism that is blocking the use of an invalid
digital certificate.

Do the macros work despite the certificate mess when the security level is
set to medium? You have to approve macros at this level, whereas at high,
you generally will not be asked to approve macros.

Hi Jon,

Thanks for the reply. The only way I get this to work is by setting the
Macro Setting of "Enable all macros". I am prevented from approving this
macro with the setting "Disable all macros except digitall signed macros"
enabled. I realize ultimately the problem exists with the certificate but I
could more easily part the Red Sea then get this vendor to correct their
certificate so I was hoping there would be a work around for the blocking of
workbooks with invalid certificates.

If you open this file with or without macros enabled and then save it,
doesn't this remove the certificate? And if it does, can you then go back
to medium security for all files? A one time hassle every time you get a
new file but...

Isn't there an in-between setting? (I have no practical experience with
certificates.)
