hello,
usually occurs when make cross-architecture upgrade. example, have 32-bit version of windows operating system, , want upgrade or install 64-bit version of windows operating system on existing system.
this behavior occurs because windows operating system upgrades supported between matching operating system architectures. 32-bit version of windows server 2003 not recognize 64-bit windows server 2008 installer engine.
so, can upgrade existing operating system same bit version, or perform "clean installation" if want install 64-bit version system.
please check kind of operating system did have , make sure got same architecture version of windows operating system.
best regards,
chang yin
