Error 1935 during distribution disk installation

[ABP34]

During installation of an application from a distribution disk I get the following error:

    Error 1935. An error occurred during the installation of assembly
    'NationalInstruments.CVI.Reflector,Version="8.0.356.0",Culture="neutral",PublicKeyToken="F83B88E0AAF4FB33". Please refer to Help and Support for more information.
    HRESULT:0x8002802F

Prior versions of this application have installed correctly. This error did not occur until I installed the evaluation version of CVI on my machine (the application was written by a coworker and I wanted to learn CVI). The eval installation had a failure (I don't remember the code) and I uninstalled it. Now the above error occurs when I attempt to install the newer version of the application.

Based on solutions to an error 1935 found on NIs website I have turned off virus and spyware software as well as updated Windows (XP Media Center). Any other suggestions?

Thanks

Hello,

This error has to do with the .NET Support inside of CVI.  There is a detection of whether the .NET Framework exists on the machine before it tries this installation, because the installer will always get the error you indicated if the .NET Framework is not installed.

Can you tell me if the machine has the .NET Framework installed on it?  What version?
Can you run the installer with the command line: setup.exe /log c:\logfile.txt  - and post the log?

Regards,

My machine does not have the .NET framework installed. I will try the install again using a log file as soon as I am able and will post it. Thanks.

Hi ABP34,

We took a look at the installer log you sent in to one our Application's Engineers and discovered at least why the error was occurring.  There are certain registry keys that Microsoft uses to indicate if the .NET Framework is installed.  We check those keys to determine whether or not to install the .NET support for LabWindows/CVI.   If they are not there, we don't install .NET support. 

In your case, you do have those registry keys which is weird because you mentioned that you don't have the .NET Framework installed. The log shows that you have both the .NET 1.1 and 2.0 Frameworks registry keys.  Now, I don't know if you had the .NET Framework installed at some point or what but the easiest solution is to install the .NET Framework and then install LabWindows/CVI.

I realize this is an old thread.

I am having the same error when trying to install new version 3.1.0. It requires .net 4, and it installs it.

No other versions of .net are installed.

I only have the issue if there is an older version already on the system. New Install work fine.
