Hard blockWhen a hard block occurs, the Setup program prevents you from continuing until the issue is resolved. A hard block occurs because the Setup program has discovered an issue with your computer that would leave Windows Vista in a damaged state if the Setup program continued. You cannot click Next to continue Windows Vista Setup. Your only option is to close the Setup program.
Soft blockWhen a soft block occurs, the Setup program has detected a program or computer hardware on your computer that will not work correctly after Windows Vista is installed. However, the program or the hardware that was detected will not leave the operating system in a damaged state. You can click Next to continue to install Windows Vista. However, it is likely that the program or the hardware that was detected will not function correctly after Windows Vista is installed.
To troubleshoot issues that may cause a hard block or a soft block, we recommend that you contact the software vendor of any programs that you want to use in Windows Vista to verify compatibility with Windows Vista. Frequently, the software vendor will be able to resolve the compatibility issue by providing one of the following resolutions:
- An update to make the current version of the program compatible with Windows Vista.
- A version of the program that is compatible with Windows Vista.
- Information about any configuration changes to make the program compatible with Windows Vista.
Step 3: Uninstall the programIf program causes a hard block during the Windows Vista Setup process, you must uninstall the program before you can continue to install Windows Vista.
Program reinstallation and activationBe aware that, if you plan to reinstall the program after Windows Vista is installed, and after you have resolved the compatibility issue, you may have to activate the program again after it is reinstalled. Sometimes, activation may be unsuccessful if the software vendor prohibits the installation of the program on a new operating system.
Activation is a process that guarantees that the program that you are using is licensed to run on the computer where it is installed. Typically, activation requires that the software vendor’s Web site is contacted over the Internet to verify the validity of the program installation. Contact the software vendor if you have any questions about the activation process for the software vendor's program.For more information about Windows Vista and program compatibility issues, click the following article numbers to view the articles in the Microsoft Knowledge Base:
