Ans: The software relies on “redemption.dll,” the core dll for functionality. It is a COM Dll, so it must be registered or present in the same folder "software.exe" resides. Please make sure that dll is present on the above said location and try to install it using regsvr32.exe, a standard Windows executable to register COM DLLs.

Ans: c:\> regsvr32.exe "[path of program folder]\redemption.dll" There is a chance that you have installed various other email migration tools from different vendors on your system, and they also use the same core DLL but different versions. COM Dlls are system-wide available, so their installation can also cause this behavior of the software. If possible, then try to uninstall them from your system. If the problem persists, please email us again at support@sysinfotools.com and mention your OS and the MS Outlook versions. It will significantly help us to identify the problem. If you have another system at your disposal, you can install our demo version on that system and check for this behavior. If things work on that system, then without uninstalling the demo version, install the full version and send us a new .info file at sales@sysinfotools.com, and we will issue a new software activation key.
