Our Adobe clients appear to have autoupdated recently to 22.002.20191
We are currently running Server 2012 R2 for some legacy business applications which are not compatible with the near OS version. The servers are in a Citrix terminal environement and we are seeing frequent pop-ups for RdrCEF.exe - Application Error The exception unknown software exception (0x06d007e) occuring in the application at location 0x749e4128. The error does not show up immediatly in all situations, but may show up a few minutes later. As this is a Citrix Terminal Server environment, when Adobe is opened for any user, multiple users receive the pop-up. With only 1 user on the server, the pop-up will show up sometimes multiple times over itself. Going to Help > About in Adobe Reader will cause the pop-up to display immediately.
Previously we were able to mitigate these issues by using a series of registry / settings tweaks:
- Running the applications in Windows 7 compatibliity mode
- Manipulating the system to point at the current Acrocef path
- Excluding Adobe from Citrix application hooks
