I've replaced my motherboard (details below) and I'm doing a full reinstall of everything.
 
When I try to install X2, I get error messages as follows:
 
...\Shared Utilities\CW100Auto.dll
Unable to register the DLL/OCK:RegSvr32 failed with code 0x3
 
(pressed "Ignore")
 
...\Shared MIDI Plugins\ChordAnalyzer.dll
Unable to register the DLL/OCK:RegSvr32 failed with code 0x3
 
(pressed "Ignore" - the process continues, and then I get:
 
The program can't start because mfc10u.dll is missing from your computer....
 
When I attempt to start, I get the final error message.
 
I have run X2 successfully since it first came out on other hardware.
 
Any help you can offer will be much appreciated. I'm dead in the water for now.

Hello Vance,
Let's try clean installing your C++ libraries:
Lately we have had a few customers update their Visual Basic C++ Libraries to the latest 2012 and that has seemed to fix some of these issues that you are reporting.


Please navigate to your start menu and type the following word: "Control Panel"
When the application appears please click on it.
Within the Control Panel please select "Programs and Features"
Scroll down until you see "Microsoft Visual C++ (year) Redistributable
Please right click on every one of these and select "Uninstall"
After this please re install these libraries using the following links
For 32-bit operating systems or 32-bit programs on 64-bit operating systems:

Thanks for the update

Was just going to recommend this based on some other posts about this issue. Just re-installing the 2010 package would probably have done the trick.
