PGPpwflt missing from network provider PGP Desktop 10.2.0
We have started getting users who's single sign on is not working with PGP Desktop 10.2.0. The entry for PGPpwflt is missing from the network provider. I have checked that PGP_INSTALL_SSO=1 and have read in a locked post that reinstalling fixes the problem. I do NOT want to decrypt the disks as part of the reinstall. The previous locked post mentions a Tech149282 which I can't find. Can someone help with the correct reinstall procedure without decrypting?
Thanks in advance.
