I seem to have the same problem as these good people,
.NET 4 installs (reporting no overt errors).. but will fail verification with this message. .NET 4 applications fail to run.
[07/22/10,17:35:35] Launching process 'Netfx40TestApplication.exe' now
[07/22/10,17:35:35] Process successfully launched. Waiting 300 seconds for it to complete.

[07/22/10,17:35:35] ****ERROR**** Verification failed for product .NET Framework 4 Full
I do get this event log error when installing .net 4.0 full version , but not the client. Of course neither one works.
CommandLine wusa.exe "G:\e1781735b278c4779d6d\Windows6.1-KB958488-v6001-x64.msu" /quiet /norestart
Steps already taken to troubleshoot this include fully uninstalling .NET 4.0 and reinstalling (both client and full); reinstalling .NET 4.0 over itself with a repair install; installing .NET 4.0 full over a client install; I've also run full disk scans
etc., and my system is fully up to date with Windows Updates.
Any one know what that error code means? Maybe it can he
