Does anyone know of a way to programmatically determine which version of the .NET framework is installed on a computer? I was thinking of trying to scan the registry, but my main worry is that a user would need admin rights if trying to use the method
View 8 RepliesI have developed a small application in VB.NET 2008. It uses .net framework 3.5. But somehow it also runs in computers with .net framework 2 or 2.5. Is there a way to determine thru code what is the latest version of .net framework the pc is running. This way I can give a warning message box that the required framework is not installed.

View 2 RepliesIs there any way (via code or otherwise) that you can tell what version of the .NET framework a particular EXE or DLL is targetting? I know the long way round would be to try and run it on a machine with just .NET 1.1 on, then if that doesnt work try it on a machine with 2.0 on, etc etc

View 4 RepliesI am writing my first application in VB 2008 Express with .NET Framework versions 2.0, 3.0 and 3.5 installed. When completed, I assume the application will need to check whether it is running under .NET Framework version 3.5 or later. I have not found any properties that I could get which would give me this information about the environment in which the application is running. Is this something that the non-user code in which my application is wrapped by the IDE checks, or is it something that I have to check myself within the application ? If the latter, how would I do that ?

Is there a way to check if the necessary version of .NET framework has installed and if it has not installed to display a custom message explaining the user what is the problem and how to download the required version of .NET framework in order to make the application work?

View 1 RepliesI need to detect if any version of the .NET framework is installed as we are deploying a .NET 2.0 app via logon script (ie XCOPY deployment) to all PCs in our network. The .NET app will be set to start when a user logs in, so we need to determine if .NET 2.0 (or higher) is installed before we deploy the app otherwise the user will get an error each time they log in. Is there any sure fire way to detect .NET via vbscript or batch file? All of the results I have found on google don't seem to be that reliable.
I have recently written a program that detects installed programs in the same way that Add/Remove Programs does but the problem with this is that even Add/Remove Programs does not seem to show the .NET framework on all PCs that have got it installed (like my home PC for example, definitely has .NET 3.5 installed but its not in the Add/Remove Programs list).
I'm writing a code that will check if .net framework 3.5 SP1 is installed before installing the program.The command I found googling around was System.Runtime.InteropServices.Runtime Environment.GetSystemVersion..I wasn't able to verify the correct .net framework version using this command.I'm currently running 3.5 SP1 and this command is showing v2.0.Is there another way to get the correct .net framework version?

View 5 RepliesHow do I programmatically increment a given version's number to the next version of the highest one?
For example if I have a file Program.exe with the following version numbers :
Program.exe 1.0.0.0
Program.exe 1.0.0.4

Program.exe 1.0.0.66
The next version number in this case would be 1.1.0.77
What's the easiest way to implement that?
You can get the version of your application sing My.Application.Info.Version. Is it also possible to set this version using code? This because I have a webservice that connects to a database and retrieves a version number.My application then compares that version number with his one, if it's old.. then it will download new files and change his version number.
View 3 RepliesMainly I ask this because I don't want to distribute both versions, and if I need to instal a 64bit .NET on an x64 PC and a 32bit .NET on a 32 bit PC then I would need to make this check in my loader application to download the correct version for the correct PC.

I wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?

View 2 Repliesconfirm the forum for this question about Visual Web Developer 2010 Express. I found a VWD Express forum, but it was in Spanish... Lo Siento. My issue is selecting a down-level, 3.5, framework version as I create a new project/website. I have figured out how to CHANGE the target framework version once the website/project is created. I have the 3.5x installed on the system and available. The articles I have seen discussing this issue, refer to a framework version selection drop list in the new project creation dialog/wizard. I do not have that option.
