How to keep digital signature?

Hi,

I need to open and modify a digitally signed Excel doc as a template

then, save to another file. But the saved Excel doesn't have the digital signature

any more. Could you have help with this?

Thanks,

We will check and fix this issue. It will take about 1 week. Thanks for your patience.

Hi Lawrence,

do you have any update?

Thanks,

We changed underline implement to structure storage file and discard COM totally. That may cause this problem. Roman is checking this issue. I will reply here when we make any progress.

This problem is fixed. Please try this attached fix.
