Hi Brian,
I know the feeling about .NET or Widows Installer problems. A royal pain.
I found that most- (maybe all-) of the time .NET versions need to be installed sequentially,
starting with the lowest version.
Checking which versions of .NET are installed is a start and I use .NET Version Detector
for that : http://www.asoft.be/prod_netver.html
Another description of this tool

I've had good luck using the tools of Aaron Stebner.
Website to keep handy - Lots of helpful info
for .NET cleanup tool and other NET articles and advice.

BTW , .NET Framework v3.5 SP1 is required to run Microsoft Maths.
It is clearly outlined on this page under System requirements.
http://www.microsoft.com/en-us/download/details.aspx?id=15702#overview
Having .NET v4 doesn't guarantee that a program that is targeted for .NET v3.5 will run
if v3.5 is not installed.
This is what it says about .NET v4.0
"The .NET Framework 4 works side by side with older Framework versions. Applications that are based on earlier versions of the Framework will continue to run on the version targeted by default."

Botched installations can cause a lot of trouble and usually the cure is
to clean up all remnants of the install and then re-install after fulfilling requirements
such as .NET etc.

Subject: Re: Net Framework and Microsoft.NET Framework
I am currently running two PCs and have been struggling to get Microsoft
Maths 4.0 onto the main PC - a Desktop.
Both machines have Win 7 as their OS.
As I download the software from Microsoft, CNET or whomsoever FINE
As I Run the software to Install it - FINE
BUT then an error message appears - "we told you that you would need >NET
Framework 3.5 +SP1"
I do not use this software often so first time here I tried to 'upgrade' to
vs 3.5 not realising that I already had vs 4 under the hood as it were.
The Install just never happened.
I tried this several times, using different sources of code.
I have tried to undo anything thatI might have done and restarted several
times!
No luck.
This must be a trivial problem and I am doing something wrong. YES must be!
IO am now beyond any comfort zone that I had.
Using Windows Update I have checked the current and past status of . NET
Framework
This looks there is the original 4 install followed by two to three
updates, can check and give you chapter & verse, followed by 9 or 10
Security upgrades - all must be after the 3.5 which would have been there.
Any other information can be provided as required.
My next action is to ! check the >NET framework status of the Laptop and
then try and install to that.
Another clue me thinks.
I would be grateful for any other useful suggested actions .
It does not help but I know a number of folk who run Microsoft Maths but all
on older OS systems.
Not sure whether they have, or need ,NET Framework!
Any suggestions gratefully received, I am off to the Laptp now!
Thanks
Brian
