The first thing to do when you encounter error code 1603 is to fix the .NET problem. You can do it by running QuickBooks Install Diagnostic Tool and it will try to resolve the matter. This is how you carry out the process.
Using QuickBooks Install Diagnostic Tool
- Close QuickBooks and any other running programs
- Download QuickBooks Install Diagnostic tool. Designate a folder or let it download to a folder and note the folder where it is downloaded and navigate to that folder once it has been downloaded.
- Install it by clicking on QBInstall_Tool_v2.exe.
- Run the tool.
- It may take about 20 minutes for the tool to complete the download, install and scanning process.
- Once the process is complete you must switch off the computer and then restart it so that Windows can install the necessary components.
- This should fix your problem.
Manual Process To Fix
- Close all running programs.
- Hold down Windows Key and press “R” key.
- The run dialog box opens.
- Type “Control Panel” in the box and click on OK.
- Now choose “Uninstall a Program” and then click on Turn Windows features on or off.
- Locate the .NET Framework 4.5 or 4.7 entry from the list and enable it by clicking on the checkbox next to it.
- Click OK and restart the computer.
However, you may find that the .NET framework is already enabled but it is not working. Then you have to repair the .NET Framework. Do this by unchecking the box and then reboot the computer.
- Go to control panel and to the Uninstall a Program feature and re-enable .NET Framework.
- Reboot the computer.
- Do this for whatever version .NET Framework is there on your system.
- If you have an older version of the .NET framework and it is corrupt you can try to download and install the latest version.
- Some users have attempted to remove older versions and also remove entries from the Registry to make sure there are no conflicts. Then the fresh installation of .NET framework is carried out.
The easy way is to first use the QuickBooks Install Diagnostic Tool. It usually resolves anomalies and the issue is fixed. Follow the manual process only if the first process does not solve your issue because it can get tricky at times to install the .NET framework. A newer version may not work and you may have to install the exact version that QuickBooks needs.
