Hello, I have a question about windows 8.1 upgrade. On my computor I have dual boot, both Windows 8 but one is 32 bit and other 64 bit. I upgrade windows 8 32 bit with no problem. When I try to upgrade windows 8 64 bit from store I got error that my CPU dont support new upgrade. When I try upgrade with microsoft file upgrade I got error that CPU don't support CompareExchange128. Here is my data from processor AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ AMD64 Family 15 Model 43 Stepping 1, AuthenticAMD HTT * Multicore HYPERVISOR - Hypervisor is present VMX - Supports Intel hardware-assisted virtualization SVM - Supports AMD hardware-assisted virtualization NX * Supports no-execute page protection PAE * Supports > 32-bit physical addresses SSE * Supports Streaming SIMD Extensions SSE2 * Supports Streaming SIMD Extensions 2 SSE3 * Supports Streaming SIMD Extensions 3 SSSE3 - Supports Supplemental SIMD Extensions 3 SSE4.1 - Supports Streaming SIMD Extensions 4.1 SSE4.2 - Supports Streaming SIMD Extensions 4.2 AES - Supports AES extensions CX8 * Supports compare and exchange 8-byte instructions CX16 - Supports CMPXCHG16B instruction So what is missing for MS to upgrade my windows 8 I don't want to do bypass check because want to know what missing to processor

Hey Gunter! You can extract your iso to some folder, find file sources\wica.dll and rename or delete it. After this you can start your installation again, all processor compatibility checks will be disabled and you can continue at your own risk.
