I usually sign forms digitally with Acrobat, but am no longer able to do so. I get a message that says "invalid provider type specified. Error code 2148073492" Can this be fixed?

Hi satpalg,

As per the issue description mentioned above, you are getting an error when trying to sign a pdf, is that correct?

Please try following troubleshooting steps:

1- Check if an update is available for Acrobat or Reader using "Check for updates" option under "Help" menu, reboot the machine after installing update and try again.

2- If that doesn't work, try the steps given in this link: Signature creation error when you sign a PDF (Adobe Acrobat 8, 9 on Windows)
