When I try to install Enviro Spase I get the error shown below.
This is because newer versions of Windows do not include this version of .NET, but they will not work with Enviro Spase. To fix this, click No and then go to this page. Once on that page, download and install the version needed by clicking on Download .NET Framework 3.5 SP1 Runtime.
If you still have problems, please contact Geotech Support.
