Resolution 1: Extirpate this installation error through the proper execution of the QB Install Diagnostic Tool
•Correctly log onto Intuit website and then proceed immediately to download the QB Tool Hub on the system by simply clicking on the relevant download link, and after that, launch the downloaded file (QuickBooksToolHub.exe) so that you can obtain the easy installation steps for the tool hub.
•Now, you just need to follow all those steps that show up on the screen in order to install the tool hub and then easily launch the tool hub to identify & strike the ‘Installation Issues’ tab so that you can reach the ‘QuickBooks Install Diagnostic Tool’ icon.
•At this step, kick off the execution of this tool by tapping the ‘QuickBooks Install Diagnostic Tool’ icon, and after its complete execution, you must reboot your computer, after which you can successfully install the QB Desktop application.
Resolution 2: Carry out complete repair of the ‘Microsoft .NET framework’ on the system to fully resolve this installation problem
•To obtain the list of ‘Microsoft .NET frameworks’, you have to first launch the ‘Control Panel’ from the ‘Start’ menu, after which you must proceed ahead to click on the ‘Programs and features’ and the ‘Uninstall a Program’ tabs successively.
•Thereafter, hit the ‘Turn Windows features on or off’ button to easily get the list of the ‘Microsoft .NET framework’ on the screen, after which you are required to identify the ‘.NET framework 4.5’ in that list.
•Now, you must mark the checkbox beside the ‘.NET framework 4.5’ if it is
unchecked and thereafter, hit the ‘OK’ button to simply reboot your computer. However, if the ‘.NET framework 4.5’ checkbox has already been marked, then you should unmark it, after which you can reboot the computer.
•At this step, you must ensure that the ‘.NET framework 4.5’ checkbox is marked after your system opens up again and then simply repeat this process with the ‘.NET framework 3.5 SP1’ and other ‘.NET frameworks’ such as 4.6,4.7 and 4.8.
•After the entire ‘.NET framework’ has been repaired correctly, you can go ahead to successfully install the QB Desktop application on the computer.
