Solution
In rare circumstances, this problem occurs when you try to remove certain shared components during uninstallation.
Complete the following steps to resolve this problem.
Using Command Prompt:
- Make note of which part of LabVIEW was uninstalling when the error occurred. It usually occurs during the LabVIEW Core-Full part, the LabVIEW 7.1 Runtime Engine part, or during both.
- When the error 1603 dialog box prompts you to continue the operation, click the Yes button.
- If prompted to restart your computer after the uninstallation completes, click the No button.
- For each part that generated an error during the uninstallation, run the corresponding MSI files manually from the CD:
- LabVIEW Core-Full -- [CD Drive]\components\lvcorefull\lvcorefull.msi (you may also download the files -- see related links below)
- LabVIEW 7.1 Runtime Engine -- [CD Drive]\components\lvruntimeeng\lvruntimeeng.msi
- Click the Repair button.
- Run the MSI file for the same part again.
- Click the Remove button.
LabVIEW 7.1 should be completely uninstalled.
