What to do if TestComplete 7.52 does not recognize .NET objects

If you are using TestComplete 7.52 and it could not recognize .NET applications, it is due to Microsoft has released some .NET Framework updates that were installed automatically on many computers by the Windows Update service. The changes are related to the core .NET Framework functionality used by TestComplete.

After the updates are installed, tests created for .NET 1-3.5 applications may stop working correctly - you may see the "Object Not Found" and related errors in test results.
