Business Plan Pro has encountered an error.... Follow


When launching Business Plan Pro, you may encounter a generic Microsoft error that says:

Business Plan Pro has encountered an error and needs to close. We apologize for any inconvenience. Would you like to send a report to Microsoft about this error?


In most cases, this indicates a problem with the .NET Framework. Repairing the .NET Framework for Windows may resolve the problem:

Tip: Due to the way Windows protects the .NET Framework, it's often not possible to entirely clean up and fix .NET on the computer. If the user has access to another computer, it is often best for them to install and use the software on the other machine instead or while trying to fix their desired computer.


For instructions on repairing a problem with the .NET Framework, we turn to one of Microsoft's developers. Aaron Stebner maintains a blog about issues with installations of components of Windows including .NET.

In Aaron's Blog he says:

All versions of Windows starting with Windows Vista include the .NET Framework 2.0 as a part of the OS, and it cannot be removed.

Here are some steps you can use to try to repair the .NET Framework 2.0 that comes as a part of Windows:

  1. Install the latest Windows service pack if you haven't yet.
  2. Try to run the System Update Readiness Tool from
  3. Try to repair the files that are a part of your OS by using the steps listed at

If none of the above help, you might need to repair/re-install Windows to fix this type of error.  It might also help to post a question on one of the Windows forums to see if someone there has any additional suggestions for you to try before you resort to re-installing Windows.

So, based upon those recommendations our instructions are to: 

  • Download the latest .NET Update from

    1. Go to Microsoft's .NET site
      • Windows XP, Windows 2000 SP4 and Windows Server 2003 install at least: .NET 2.0

      • Windows Vista install at least: .NET 3.5

      • Windows 7 install at least .NET 4.0
    2. Click the Download button to download the dotnetfx.exe file.
    3. When prompted, choose to Save the file to the Desktop of your computer.
    4. Once the download has completed, run the dotnetfx*.exe file and follow the steps to install the .NET update.
    5. Restart the computer and see if the problem persists.
  • Run the System Update Readiness Tool

    1. Go to the following Microsoft Web site:
    2. Scroll down to the "Resolution" area
    3. Click the appropriate link for your Version and Edition of Windows. For example if you're running the 64 bit edition of Windows 7, you'll want the link labeled "All supported x64-based versions of Windows 7"
    4. Click the orange "Download" button on the next page.
    5. Once the download has completed, run the .msu file that was downloaded and allow the update to install.
    6. Restart the computer and see if the error persists.
  • If the problem still persists, try to repair the system files that are part of your Operating System by taking the steps at:
