Opened VS2010 Beta 2 (Premium Edition) for the first time. Tried moving some panes around. Then I tried to create a new C# WPF project and Visual Studio crashed. Upon restart it told me that a Modal Dialog is open and it cannot start. I decided to close all apps and reboot. Now, when I try to start Visual Studio 2010 Beta 2, it attempts to start but fails giving me a "The application cannot start." error and the VS window pops up with only a black background. I tried doing a "devenv /ResetSettings", but the problem continues to persist. I am going to reinstall and see if that will fix this issue.

Uninstalling and reinstalling Visual Studio 2010 Beta 2 did not resolve this issue - the application still fails to start with the "The application cannot start." dialog.

devenv /reset from the command line displays:

Microsoft (R) Visual Studio Version 10.0.21006.1.
Copyright (C) Microsoft Corp. All rights reserved.

The evaluation period for Visual Studio Trial ends in 251 days.

The application cannot start.

WinDbg output of a devenv.exe app start (demonstrating the problem) is attached to this report.

### I figured out the cause of this bug at least for my specific case, see the Workarounds section for details, which may or may not apply to your startup issue!
### "Steps to Reproduce" have been updated with the simplest way to produce this error from a fresh VS2010 Beta 2 install

IMPORTANT NOTE: It seems that VS2010 Beta 2 has a problem with non-True Type/Open Type fonts being used for editing. If you change your font to a non-True Type/Open Type font such as Terminal or Courier (not Courier New), you will not be able to open/edit files source files. VS2010 may also fail to start, forcing you to reset it back to its initial state.

This is a HUGE GAFFE in this release, since very many developers depend on crisp pixel aligned raster fonts for development. The Visual Studio editor absolutely MUST support such fonts, as it has from its inception.

Apparently, Microsoft has decided to no longer support raster fonts in Visual Studio. Therefore those of us that use Courier, Terminal, or Fixedsys for editing are effectively forced to use a TrueType font like Consolas. 

Since this decision is final and based on the fact that VS 2010 is transitioning to WPF, at the very least, the ability to control inter-line spacing should be present to enable users of raster fonts such as Terminal, to continue to have a relatively high line count on the screen.

VS 2010, as of Beta 2, inserts a gratuitous amount of space between lines of text. In fact, if a font such as Consolas 8 pt. is selected and code is copied from VS 2010 Beta 2 and pasted into MS Word 2007, one can see that VS 2010 is adding some 25% of additional space over what is present in MS Word. This greatly reduces the vertical line count per screen. If vertical line-space control cannot be added for the RTM, at the very least vertical line-spacing should be reduced by at least 20% to coincide with the reasonable spacing between lines in MS Word. This will greatly increase code readability, because the user will be able to get the same line count using Consolas 10 pt. as he does now with Consolas 8 pt.

If you are running on Vista or Win7 and typically run Visual Studio as an Administrator, be sure to run the devenv workaround from an elevated command prompt

32-bit: C:\Program Files\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe /resetuserdata
64-bit: C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe /resetuserdata

Otherwise, be sure _not_ to run it in an elevated command prompt.

When will the next VS2010 (Beta3 or RC1) will be released?

Hi KonamimanMSX, mgoldshteyn, and other readers,

There are two issues with similar symptoms, and it looks like different commenters are hitting one or both of them. I'll try to clarify:

1.) The Editor issue Sean described is a problem with raster font settings. VS 2010 and WPF 4.0 do not support raster fonts, but Beta2 has a bug where instead of falling back to the default font (Consolas for English systems), the editor will fail to load. This usually allows VS to launch but gives the error message "Object reference not set to an instance of an object" when opening a file, though it can sometimes give the error message "The application cannot start" when launching VS. The workaround is to go to Tools->Options->Environment->Fonts and Colors and change any raster or bitmap font settings to a TrueType font. Running "devenv /resetuserdata" will also resolve the issue, though it will reset all of your settings to the defaults and therefore change more of your preferences than is necessary to fix the problem. You can read more about this issue at the link Sean provided:

2.) There is a separate Shell issue that can happen without raster font settings. This usually gives the error message "The application cannot start" when launching Visual Studio. The workaround is to run "devenv /resetuserdata". You can read more about this issue at

I'd like to stress that both of these issues have been fixed since Beta2, which is why I'm resolving this Connect bug as Fixed. If anyone has further questions about either issue, commenting on the appropriate blog post will probably lead to a faster response, though you're of course welcome to comment directly on this Connect bug if you prefer.

Thanks to all of you for trying Visual Studio 2010 Beta2 and sending your feedback!

Please do not close this issue as "fixed". I had the same problem and it had nothing to do with raster fonts. I was able to add and edit solutions, projects and files for some days, and suddenly it failed with the "The application cannot start" error. It has happened twice to me.

Hi mgoldshteyn (and other commenters on this thread)

Thank you for reporting this issue. Unfortunately, VS 2010 and WPF 4.0 do not support raster fonts and we were not blocking the scenario where a font preference was imported from VS 2008. To learn more about this issue and how to workaround it in Beta 2, please take a look at our blog post on the subject:

Given that we've fixed it such that users can't get into this state in builds after Beta 2, I'm resolving this issue as fixed. If you have any more feedback on raster font support, please feel free to respond to the blog post.

Had exactly this problem.
VS 2010 had picked up the raster font I used in VS 2008.
Changing the font name fixed it for me.

Same problem here, and the devenv /resetuserdata. But now I have to reconfigure all tool windows and toolbars. :-(

ersheido, did you try "devenv /resetuserdata"? [making sure what you meant by /reset]
Posted by ersheido on 10/26/2009 at 6:16 AM
The workaround to reset the environemtn is not working for me. I'm on Beta 2 Professional. Just before the weekend, I was using it without any problems, put my laptop in Standby mode, and when I came back this morning, the battery was drained for some reason. I turned on the PC and tried to ope VS, but got the generic "Application Cannot Start" error immediately after the splash screen.

The command devenv /reset produces the same error ("The application cannot start.") for me, but on the command line.

@Strumpflohner, see the workarounds it might help you.

It is the same issue in my case. I also opened a new Web project, moved out the Solution Explorer from the VS main frame and it crashed. Restarting it results in the error message. Also restarting my Vista (x64) didn't help. I was using VS2010 beta2 ultimate
Posted by Carlos MD on 10/22/2009 at 2:52 PM
It works to me too. Thanks a lot.
Posted by bwt on 10/22/2009 at 2:14 PM
MuraliP, your tip works as well! I have added it to the Workarounds section as an easier solution than manually editing the registry.

Posted by MKPotluri on 10/22/2009 at 1:59 PM
Have you tried "devenv /resetuserdata"? Persistence of the crash after reinstall makes me think it has something to do with your profile corrupted. /resetuserdata should re-create your profile for VS.

Same bug:
Opened VS2010 Ultimate beta 2 and tried some c# projects. Then Visual Studio hang up so i restarted the computer and get the "application cannot start" message. I uninstall Ultimate and install profesional version of beta 2. The problem was solve until VS2010 Profesional hangs. Then i have the same message againg. I have tried repairing options from control panel without success.
Please tell me something to solve this issue. Thanks

This is a serious show stopper for people who want to try Beta 2. So, if you experience this problem, please vote this report up using the green up arrow at the top of the screen. Hopefully, MS will give this the attention it deserves and post a resolution to the problem.

Same bug:
Opened vs2010 beta 2 ultimate for first time. Creating a project c++. Editor say "it cannot test10.cpp" wich was created by wizzard (the file is on disk). Now, i try to open the created project instead of using create wizard, it cannot read the cpp, but it's not a file acl problem (opened it successfully with notepad).

I close gracefully all application, reboot and now I have "the application cannot start" when launching vs2010.

I have reinstalled vs2010 with same problem.
