Starting with Teamprise 3.0, extracting the Teamprise installer archives with the built-in Windows archive explorer may corrupt the extracted files. This error happens more often when using the copy/paste method within the built-in Windows Explorer. An error is not always displayed if the extracted files are corrupted. Teamprise clients will not run correctly if the extracted files are corrupt.
To resolve the issue, remove the current installation that you have installed. Extract the Teamprise client archive file again using the Windows Extraction Wizard (by right-clicking on the ZIP file and selecting the "Extract All" option). You can also use a ZIP utility from a different vendor (no others are known to corrupt the extracted files).
