We are using version 251 - the machine is WIN server2003 SP1 x64.

The documents says version 251 support x64, am I right ?

Please help...

Thanks in advanced,

64-bits XP, 2003 and Vista are supported starting version 2.50-g

Please check that you are running Install.exe from a folder containing all the files you got with the PDF Converter and that you are logging to the machine as Administrator.

I am running Install.exe from a folder containing all the files I got with the PDF Converter (after installed setup.exe) + I added acfpdfuia64.dll and I have administrator privilege -> same error messages;
what else can I do ?

Your 64 bits system is AMD (x64) or Itanium (IA64)?

If it is AMD please make sure that both 64 bits dlls are in the same folder as the installer: acfpdfuiamd64.dll and acfpdfuamd64.dll

If it is Itanium please download the 64 bits dlls from www.amyuni.com/downloads/legacy_drivers.zip

Hope this helps.
