I see that for me at least, the certs that I can sign a form with are in the personal certificate store. But if the cert dialog doesn&#39;t pop up at all, that can&#39;t be the issue. Want to email me your forms and cert and I can sign them for you and send them back? That would at least get you un-stuck. You can email me via the forum, I&#39;ll reply and we can coordinate that.... The only other suggestions I have are the obvious - make sure Windows updates are installed, run a repair on InfoPath....I guess you could uninstall and reinstall InfoPath....https://www.infopathdev.com:443/forums/thread/123016.aspxMon, 18 May 2020 21:25:22 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:123016Jay@Work0https://www.infopathdev.com:443/forums/thread/123016.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=123016<p>&nbsp;Each year I have to renew my certificate from our local CA, then open a couple of Infopath forms and go to security and trust to select the renewed certificate and then deploy the form again.<br />I have done this on these particular forms for 5 years without any issue.<br />User&#39;s can no longer open the form as the certificate expired. I missed my annual reminder during lockdown!<br />So I open the form in Designer and it tells me the certificate is expired and to click ok to remove it, which I do.</p><p>Then I go to security and trust and check the box to &quot;sign this form template&quot; and then I click select a certificate.<br />Nothing happens. No dialogue box pops up so I can select the correct certiciate, no dialogue hiding in the background. This happens on each of the forms and now I am stuck.<br />I have tried running Designer as administrator, checking that my current certificate shows in Certificate Manager, I have rebooted my PC.<br />Any ideas?&nbsp;</p>
