In debugging mode, exceptions such as testwindowpackage. initialize failed with exception can be found in c: \ Users \ liudy. smnpc \ appdata \ roaming \ Microsoft \ visualstudio \ 11.0 \ activitylog. xml. I basically don't know about DU Niang. I asked Gu Ge and finally found a solution (but I don't know why ).

Step 1: start --> all programs --> Microsoft Visual Studio 2012 --> Visual Studio Tools --> vs2012 developer command prompt (run as Administrator)

Step 2: Run devenv/safemode)

Step 3: Enable vs normally and run normally

For details, see:

1. open Visual Studio command prompt (2010) under Start Menu-> All Programs-> Microsoft Visual Studio 2010-> Visual Studio Tools (run it with administrator privilege: right-click the program-> Run as administrator );

2. Try some devenv switches in Command Prompt:

A. RunDevenv/ResetsettingsTo eliminate the cause of your upted settings.

B. RunDevenv/resetskippkgsIn command prompt.

C. RunDevenv/safemodeTo see if you can apply it correctly. This can eliminate the possibility that third party add-ins or packages are causing problems.

3. Reboot the machine inSafeMode. This can be isolate some third party application/driver's interference.

4. Switch and try a new user account. This can rule out the possibility of your upted user profile.
