The Aspera Enterprise Server/Connect Server/Point to Point/Client application might encounter the following error:
JET RUNTIME HAS DETECTED UNRECOVERABLE ERROR #3
This problem is caused by a mismatched DLL (dynamic link-library).
One reason for this error can be an incomplete upgrade of the Aspera product (some DLLs might have been in use and not upgraded). To rectify the problem, uninstall the Aspera product, manually delete the bin and lib directories from the Aspera installation directory (C:\Program Files (x86)\Aspera\<Product>), and reinstall.
A second possible reason for this error is bad system DLLs as a result of using an antivirus system such as McAffee, Symantec, Sophos, etc. These packages replace system DLLs with their own version. To rectify, you have to uninstall the antivirus package and make sure the problem no longer occurs. It is not sufficient to turn off the antivirus services (because the bad DLLs will still be present on the system). Please note that uninstalling the antivirus can leave the Windows computer in a pretty bad state - this happens, for example, if you ran Windows system updates while using the antivirus, and the update didn't correctly install all the necessary DLLs. This is an unfortunate reality of antiviruses on Windows systems and there is nothing the Aspera application can do to avoid it.
