Step 1 – Use The “Windows Installer CleanUp Utility

To fix the problems you’re seeing, its’ recommended you download the Windows Installer Cleanup Utility here, and then use the program to fix the problems you may have on your PC.
Step 2 – Ensure You Are Installing The Program To A Non-Encrypted Folder
The “Windows Installer” program cannot install software into non-encrypted folders, meaning that if you are trying to install into such a folder, errors such as the 1603 problem will show up. To fix this, it’s recommended that you make sure that you are installing the application into a non-encrypted folder – which can be simply done by ensuring your PC is able to install into a particular hard drive / folder.
Step 3 – Make Sure You Are Installing To An Actual Hard Drive
The way to fix this error is to then make sure that you’re installing the program onto an actual hard drive. Many people will actually try and install programs on “substitute” (virtual) drives, which will not only confuse Windows but make it unable to process the settings that it requires to run. To fix this issue, it’s recommended that you make 100% sure that you are installing the program onto an actual hard drive on your PC, and not a virtual drive.
Step 4 – Clean The “Registry” Of Your PC
A “registry cleaner” is a central database which stores vital information & settings for your computer. Although this database is highly important, it’s continually causing a large number of errors on your system which can only be fixed by using a reliable registry cleaner program. This works to not only ensure that your computer is able to read all the settings that it requires to run, but will be able to install the programs that it needs as well. If you’re seeing any errors on your PC, it’s recommended that you use a registry cleaner program to scan through your system and fix the potential problems that your system may have.
