Microsoft only scanned this file for viruses. Microsoft used the most recent virus scanning software available as of the date the file was posted. The file is stored on servers with enhanced security, which helps prevent unauthorized changes to the file.

Note. The data collection generates a collapsed .NET Framework installation logs .cab file. After the logs tool procedure, a .cab file, most commonly named “FixDotNet*.cab” or similar, is created and stored for the current desktop user (assuming they are running in the user interface) or a specific location. After the wizard completes, the tool sends the .cab file with the logs to Microsoft.

The FixDotNet*.cab file is always on your desktop (or in a specific location), whether you decide to send the data to Microsoft or not.

When using the /q option, many of us have recommended that you also use most of the /logs options to store data in a specific location, or allow network sharing to support emergency scenarios.

Squelch Coupled Mode Added support for passive mode on the control line for the product. The “Now” tool does not assume that you simply run a user interface procedure. Therefore, the task canBut automate.

Preference is given to a modern optional command line switch to allow repairing specific versions of the network .Framework to undo current repairs of other installed versions almost at the same time.

The file generated by the recovery log tool can now optionally be hidden in a user-specified location using a command line option. The %temp folder is in silent or passive mode.

The new method allows you to run the recovery tool in log collection mode only, without applying patches or patches. This option allows forensic logs to be collected before the actual corrections are added.

New optional support will be added to disable any data collection in automatic or passive mode.
