Always receive AccessViolationException

Question

I am trying use MS Visual C# 2010 Express to learn C#. But I ALWAYS recieve an AccessViolationExcpetion. Even if I simply start a new project, with no code of my own, when I click the debug button, I receive the following error. Any help would be appreciated.

System.AccessViolationException was unhandled

Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Source=Microsoft.VisualStudio.HostingProcess.Utilities

Hi John,

This is really wired. Could you please have a try:

1. Run Visual Studio as Administrator.

2. Execute devenv /setup under Visual Studio Command Prompt.

3. Check your hardware and ensure that drivers are installed correctly (Display drivers especially).

 

Wish this helps.

Answer 2

Sounds like a bad installation to me.  Try running a repair on VS.

Hi JohnC5,

It's really strange that the IDE reports an AccessViolationExeption with no code in the project, please have a try as below

 

1. Restart your MS Visual C# 2010 and build a new project, debug it without code in it;

 

2. If the suggestion above doesn’t work, you can try to repair your IDE, put your Visual C# 2010 disk into your CD-ROM and double click the setup to run it, you can see the setup welcome screen, then click Change or Remove Microsoft Visual C# 2010, you will find you have run the Maintenance Mode, after the setup program loading the components in few minutes, click the next, and then click the Repair/Reinstall link to repair your Visual C# 2010

 

I wish the suggestion above could help you.
