This error might occur after you move a project from one location to another on disk. To build the database, you must log in with an account that has Modify permissions for the FilePath\Bin\Data\Temp directory, where FilePath is the path to your project.

  2. Open the shortcut menu for the Temp folder, and then choose Properties.

  3. In the Temp Properties dialog box, choose the Security tab, and then choose the Edit button.

When opening a project that is stored in a Source Code Control repository, you may encounter one of several errors related to importing a key file. For projects that are signed with a certificate, the certificate must be present on every development computer that will check out the project.

  2. Copy the certificate (.pfx) file with which the project was signed, and then save that copy to the local computer.

  4. In the Certificate Import Wizard, choose the Next button.
