Troubleshooting
Installation error: “setup cannot copy the file setup1.ex_ …”
Fix the “Setup cannot copy the file Setup1.ex_” installation error, usually caused by a Setup1.exe left from an older install.
This error usually indicates that a file named “Setup1.exe” already exists on your computer (most commonly in the Windows folder), probably from a previous installation of software.
To resolve the problem, click on your Start button, choose Find > Files or Folders and search your hard drive(s) for “Setup1.exe” (without the quotation marks), and rename or delete it. Then re-run setup.
