You start a new job. You want to install some fun software on your laptop and get an error message which indicates that the software is not on the ________________ list so it cannot be installed.

This is one of Windows features that allows administrators to prevent their users from installing unwanted software. Your IT or administrator probably wants you to use the laptop for work purposes only. To undo this, you must have the administrator privileges (with admin log in credentials and rights). You can check if you are using the admin access from your laptop. Simply follow the steps below:

1. Click / Press Start Menu at the bottom of your screen.

2. Typed in timedate.cpl and wait for the Date and Time prompt / dialogue box to appear.

3. Click on change date and time settings.

4. If your APPLY button is disabled, therefore, you do not have the admin access or account.

Second reason, you have used a corrupted installer. This is a normal error for installers that have been downloaded from the internet and copied to a removable media but the copying did not happened correctly. To fix this error, you might want to UNINSTALL and RE INSTALL the software. This time used a complete and uncorrupted installer. To uninstall the software simply go to Control Panel and look for Add / Remove Programs.
