Error: 'There was a problem installing .Net..'
Description

During the installation of Sage software one of the following error messages may appear:

'There was a problem installing .Net 3.5. You need to install .Net 3.5. manually before attempting to reinstall.'

'There was a problem installing .Net 4.6. You need to install .Net 4.6. manually before attempting to reinstall.'

'There was a problem installing .Net 4.7. You need to install .Net 4.7. manually before attempting to reinstall.'

Cause

This is because either Microsoft .NET Framework 3.5, 4.6 or 4.7 isn't enabled on your computer. This framework is required for your Sage software to run correctly.

  • If the error refers to .NET 3.5 - Re-enable Microsoft .NET Framewok 3.5 and try to install the Sage software again.
  • If it refers to .NET 4.6 or .NET 4.7 - Download and install the Microsoft .NET Framework Repair Tool.
