I have a fresh installation of Windows 7 32-bit (updated through the system and Windows Update) and I need to install an Ergo525 mouse. The mouse is working properly, is recognized by Windows 7 as Ergo525, it changes sensitivity correctly but to custom setup four extra buttons (two change the volume now-useless on a notebook), I need to install Genius ioCenter.exe (they do not supply only a mouse driver). When I do that even under XP/Vista compatibility(as it worked fine under Windows XP SP3) this pops up:

"Microsoft Visual C++ SP1 Redistributable Package(x86). Command line syntax error. Type Command /? for Help."

I then restart but when I try to run ioCentre file(gTaskBar.exe) again even under compatibility mode) I get this message:

"C:\Genius\ioCetre\gTaskBar.exe The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use command-line sxstrace.exe tool for more detail."

I have been trying to sort it out myself for hours but am utterly helpless.

By the way, this is rather a productivity issue, so if there is any other program to configure the extra buttons on my mouse, I'd be more than happy with that solution.

Problem solved. It was of course a software/driver version issue-the manufacturer offers V1.3.04, Driver Genius software for driver updates downloaded v1.3.2.1 and everything was flawless. Driver Genius is a paid program, I am mentioning it just to explain what worked for me in case somebody else runs up against this issue too. It might save him/her the hours it took me.
