Error code: 127 only under 64 bit Versions

[unexpected]

Hello all,

I have installed AfterBurn 3.2c on my machines for Max8, Max9 x32, Max9 x64, Max2008 x32 and Max2008 x64 on Windows XP Pro 64bit.

Only under Max9 x64 and Max2008 x64 comes up the following error message:

Max9 x64:
c:\Program Files\Autodesk\3ds Max 9\plugins\Afterworks\Afterburn\AfterBurn.dlr> failed to initialize.
Error code: 127 The specified procedure could not be found.

Max2008 x64:
c:\Program Files\Autodesk\3ds Max 2008\plugins\Afterworks\Afterburn\AfterBurn.dlo> failed to initialize.
c:\Program Files\Autodesk\3ds Max 2008\plugins\Afterworks\Afterburn\AfterBurn.dlr> failed to initialize.
Error code: 127 The specified procedure could not be found.

The pathes and the plugin.ini are allright and the files are in the folder.
With all other Maxes there is no error message, so what's up there with the 64bit versions???

Any idea?
