The solution was to install a full version of .NET 4.0. Windows 7 comes with a partial installation so it appears that the program is present. But it is not the full-blown program. You can download the full .NET 4.0 from the Microsoft website. After installing it, DWG TrueView installed normally.
Here's my findings as I'm experiencing the same issue with 2013 TrueView (error telling me I need to install .NET framework 4.0 SP1
< Installed .NET Frameworks >
.NET FW 1.1
.NET FW 2.0 SP 2
.NET FW 3.0 SP 2
.NET FW 3.5 SP 1
.NET FW 4.0 Client
.NET FW 4.0 Full
I've installed the latest MS has to offer, and still, I can't get this to run. I'm using Windows7 Professional x64. Help
We had a similar problem. It looked like .NET 4 Full was already installed, but we kept getting the minimum .NET 4 sp 1 message when trying to install DWG Trueview 2013.
Installing Microsoft .NET Framework 4 KB2468871 solved our problem.
Hope this helps.
Windows XP 32-bit -- *** FIXED ***
We have several XP-Pro 32-bit machines. Even after the suggested .NET 4.0 Client & Full install, none of our machines would get past the “.NET 4.0 SP1 or later required” message. The TrueView installer is specifically checking the registry for installation of Microsoft KB2468871. Even if you’ve just downloaded and installed .NET 4.0, the TrueView installation will fail unless update KB2468871 is also installed.
Filename for XP 32-bit: “NDP40-KB2468871-v2-x86.exe”
I see another poster just discovered the same solution. I had to use procmon.exe to see the registry query.
I am trying to install TrueView 2013 64 bit on Windows 7 machine. I have been getting the same .Net 4.0 not installed message described above but nonoe of the fixes described has worked for me so far. I have uninstalled and re-installed .Net 4.0 from Microsoft, installed the 64 bit version of the patch from KB2468871 all to no avail. Is anyone else continuing to suffer this problem or are there any other ideas to try?
