Hi GaryLynn,

Welcome to the MSDN forum.

Firstly, you need to check the version of VS when the application created and the features the application used. If the project you got was created using higher edition of Visual Studio or uses some of those advanced features. You can not open it with the VS2008 Express version. So you can try to use higher version to open the application, such as VS2008 ultimate or professional version. Or add the requirement environment to the VS2008 Express version. 

If you have checked the version of VS and doesn’t find any issue. you can add the VS2008 Command Prompt in the Tool option in VS2008 and Type the below command and press enter.

devenv.exe /resetskippkgs

hope it helps.

Answer 2

first, under Help >> About Visual Basic 2008 Express Edition, do you have Microsoft VisualBasic 2008 listed under the Installed Products?

1. the simplest solution to try is open Control Panel in Windows >> Programs (depending on which OS you are using), scroll down to Microsoft Visual Basic 2008 Express Edition with SP1. Click on that and try a Reinstall/Repair

try opening the project

2. if that doesn't work, in the Command or Immediate Window, type:

>devenv /Setup (devenv.exe)

when that is done type:

>devenv /ResetSkipPkgs (devenv.exe)

and finally:

>devenv /ResetSettings (devenv.exe)

after running all of these, close Visual Studio, then reopen it and see if yourproject will open properly
