Attempting to install ProSeries Professional or Basic editions will result in one of the following errors:
- Error: Fatal Error During Installation (1603)
- Error: General Windows Installer engine error. Increase disk space requirement in Setup.ini and try again.
Typically these errors will occur when the ProSeries Entitlement client fails to install. This is the Intuit component that allows some of our products to license with our system. It uses Microsoft .NET Framework in order to function.
When errors such as this occur during the install of ProSeries, the root cause is commonly a missing or corrupt version of .NET Framework. Different versions of .NET Framework are used depending on the year of ProSeries and the version of Windows. This is why one year of ProSeries may install fine but another year may have these errors.
