Hello Dave,

It seems to be a .NET installation error. Did you already tried this procedure? http://answers.websitex5.com/post/23939

Hello Claudio - I have not. I tried searching the support site several times and didn't see this one come up at all. I will give it a try and check back after I'm done.

Hello Claudio,

I tried the suggested procedure - including removing NET 4.0 first. However, NET3.5 doesn't want to install on my system for some reason. I've tried several times, to no avail. I am curious though - I've got V9 working fine on my desktop tower and only have NET 4.0 installed on it and there are no issues. Any suggestions?

Does it show an error message?

Hello Claudio;

   I didi some research with Microsoft, and I understand now why I didn't see NET3.5 in the program list. Windows 7 has NET3.5, 3.0, 2.0 etc. embedded in the operating system so they are no longer add-on packages. Only 4.0 and 4.5 are. For 3.5, one only has to go in and trun on the 3.5 features (which I did), and still have teh same problem. The error that comes up first is the "Visual C# Comand Line error" pop up window, and the error attempts to seek a solution on the internet. If I close it, the activation loop starts again. It would appear that the error lies in the C# command compiler somewhere. I've done a remove of NET4.0 and a repair. I seem to recall that I had to request some kind of activation code the last time I did this with Version 8. Is that the case here? I've enclosed a jpg of the error I get after I plug int he license code, etc.

Hi Dave,

You're right, Windows 7 comes with .NET 3.5 preinstalled. Anyway, I've found that installing/deleting new software on a pc can corrupt .NET.

There's a .NET cleaning tool which can reset your .NET framework installation. Use it to remove all your .NET installations. You can download it from here:http://blogs.msdn.com/b/astebner/archive/2008/08/28/8904493.aspx

Then reinstall .NET 3.5 from here:http://www.microsoft.com/download/en/details.aspx?displaylang=en&id=22

If it doesn't work, use the .NET Verification Tool to get more informations about the problem and send me the logs:http://blogs.msdn.com/b/astebner/archive/2008/10/13/8999004.aspx

Thank you!

Claudio - I've been reading the astebner blog, but this process won't work since 3.5 is built into the OS. Matter of fact, his blog specifically indicates that - quoted here: ("One important note – as indicated above, the cleanup tool will not allow you to remove a version of the .NET Framework that is installed as part of the OS it is running on. " ).  On that premise alone, a 3.5 install won't work in Windows 7 ... it's built in.

So, the only one it will clean and remove is V4.0. I've already removed 4.0 and used the verification tool and it comes up clean.  

What about the Visual C# error? Is that related to the activation loop? I've looked through the blogs about this and no one else who's run into the activation issue seems to have that problem.

I don't want to have to go back to V8 on this one. I'd prefer to get V9 running if possible. I've checked the install list on both ny desktop and laptop, and can't find anything unusual - yet my desktop allows to install V9 and activate it with no issues.  

Hello Dave,

As I said, some Windows 7 pcs I've found in the past had a corrupted installation of .NET 3.5.

I've found this post: http://blogs.msdn.com/b/astebner/archive/2007/03/26/how-to-repair-the-net-framework-2-0-and-3-0-on-windows-vista.aspx

It explains how to repair .NET 3.5 on Vista but it applies to Windows 7 too. It should solve your problem.

Hope this can help you!

I will check it out and get back to you...
