Installing 3cx system on Windows 7 64 bit

[varietel]

Has anybody been able to install 3CX V.9 on Windows 7 Home Premier 64 bit successfully. I get the following error in my installation:
Operation failed with 0x8007000B
An attempt was made to load a program with an incorrect format.
It was able to install it on Windows XP successfully.

I can't help with the error code, but I'm running it on Windows 2008 R2 64-bit with no problems. The code base is similar between Windows 2008 and Windows 7 so I would think it would work. One thing you could try is to ctrl+ right-click the installer and choose "Run As Administrator" when you install it. I've had to do that a few times to make things work with other programs.
