FAQ: How can I get rid of the error "Could not write to the registry" on Windows 2000?

When using OdbcRegTool with IIS5 on Windows 2000, you might see the following error:

Could not write to the registry

This error stems from the new default application protection setting of Web sites: Medium (Pooled). With this setting in place, the ODBC Installer functions used by OdbcRegTool cannot write to the ODBC portion of the registry as necessary.

You can circumvent the problem by changing the application protection setting to Low (IIS Process). See the following screenshot where to make this change.

If you are not comfortable with making this change for the entire Web site, you can put OdbcRegTool related scripts in a separate folder and change the application protection settings for only this folder.
