Windows 7: Error 1603 - how to fix the problem

The error message 1603 under Windows 7 does not say much about the actual error. You can find information on troubleshooting in this practical tip.

This code says that you do not have permission to install and occurs when installing Windows Installer packages:

• Therefore, try to run the installer as an administrator.
• To do this, right-click on the file and select "Run as administrator". You must confirm this process.
• When choosing the installation folder, make sure that you have the appropriate access rights.
• Usually, you should always install such packages on the local hard drive, i.e. where your Windows distribution is located.
• Installation on external hard drives or the like can lead to this error.
• In rare cases, the installation is also blocked by other programs.
• If you have a so-called tuning program, such as TuneUp Utilities, switch it off for the duration of the installation.
• It can also happen that the installation is blocked by the firewall or the antivirus. You should therefore also deactivate these at short notice.
