The new IpMaster v2.1 will operate on Windows XP, Windows 2000, Windows Me, Windows ’98 2nd Edition. Due to the new warp-capture engine architecture, there a couple of Windows components that must be on-board for IpMaster v2.1 to use... they are : 

1 ) IpHlpApi.dll – Can be found on your installation CD(s), or simply do a Google search on IpHlpApi.dll to find a myriad of sites that have it for download. IpHlpApi.dll can also be obtain from Microsoft, www.microsoft.com. At Microsoft also do a search on IpHlpApi.dll. 

2 ) WinCap - included in the IpMaster setup processes. During the IpMaster v2.1 installation, the WinCap procedures were traversed and should now be on-board. WinCap can also be obtained from a variety of sources on the internet. http://winpcap.polito.it/  is a dependable site for WinCap downloads and installs. They have an Auto-Installer download. WinCap is available across all Windows platforms.

At the end of the Setup process, open your Programs menu...right click and "Sort by name". The IpMaster menu will appear.

Then you can restore them to the newly formatted drive and re-install.

IMPORTANT NOTE : You must Un-Install IpMaster, using the Programs->IpMaster->Setup application, then ZIP the install files into an IpMaster.zip file, in the same location, when wanting to backup IpMaster and Re-Install later. This must be done to comply with IpMaster's copy protection policies.
