When installing Groupwise 2014 clients, we found that some programs like 7-Zip, WINZIP, and others will cause Groupwise to crash, or say "Access is Denied" after unzip or during the unzip of the EXE file.
Better idea is to NOT use the computer's installed unzip, and instead use the Windows Explorer unzip function or another set unzip inside of the EXE (best a ZIP file) to avoid conflicts, bad installs, and NO installs working when Anti-Virus is re-enabled.
