You have to re-attach all of the infopath form to their own library (2-2500 files/hour).https://www.infopathdev.com:443/forums/thread/105631.aspxThu, 25 Feb 2016 15:50:32 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:105631JcProdata0https://www.infopathdev.com:443/forums/thread/105631.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=105631Hello, That makes two weeks I'm looking for a solution without success, I have a concern with infopath published on a Sharepoint They had a certificate created in 2009 and expired in early February. The worry is that the developer is no longer there and that historically I do not know who it was. And that the certificate is used by a lot of infopath, over a hundred. We remake a new certificate with a new key, the new infopath work but can not open old. We have this error message: "Infopath cannot load this form. Either the signature is corrupted, or the certificate used to sign this form is expired or revoked." Should I find the machine that generated the certificate? is it possible to remove this certificate? What do you recommend to allow access to these ancient infopath? I found this post but I do not have the ability to simply renew the certificate with the same key or I do not know how ... : http://www.infopathdev.com/forums/p/25971/90174.aspx I know nothing about infopath, thank you in advance for your help Regards
