I have installed Kayako Desktop v4.2.0.683 Stable Release with succes. I did it by reading several community forum threads so I'm going to lay down all the information here. Install all this into a WinXP bottle:
- Windows Installer 4.5 - WindowsXP-KB942288-v3-x86.exe (http://www.microsoft.com/en-us/download/details.aspx?id=8483)
- Framework .NET 2.0 (From Crossover)
- Windows Internet Explorer 7 (From Crossover)
- CrossOver HTLM engine, if not already installed in the bottle (From Crossover)
- Windows Internet Explorer 8 (http://www.microsoft.com/en-us/download/details.aspx?id=43)
- Kayako Desktop (http://hotfix.kayako.com/product.php?product=8)
Tips: Install Windows Installer 4.5 Redistributable from the Microsoft Download Site. Select "restart later". Start the Task Manager in the Control Panel and end the "update.exe" process.
