If Windows Vista Service Pack 1 is installed on a Vista x64 machine, ANSYS 11.0 SP1 will not install. The error message is:
"This installation cannot identify your processor architecture as being compatible with AWP for Windows XP x64 Edition".
A Tech Note has been written for this issue - see TECH NOTE 2008-1 - 10 Mar 08 under Online Support > Technotes on the Customer Portal. The Tech Note contents are:
On a 64-bit machine the ANSYS install checks the "PROCESSOR_IDENTIFIER" environment variable for EM64T or AMD64.
This check is in place so that an attempt is not made to install the x64 version of ANSYS 11.0 on a 64-bit Itanium machine. Microsoft changed the contents of this environment variable when they released Service Pack 1 in that it no longer displays EM64T or AMD64.
1. Open a Windows command prompt
2. Type: set proc
3. Copy the contents of the PROCESSOR_IDENTIFIER environment variable with your mouse
4. Type: set PROCESSOR_IDENTIFIER=EM64T(for Xeon 64bit) or AMD64(for Opteron), followed by a space and then paste the contents of the PROCESSOR_IDENTIFIER environment variable at the end.
5. Rerun the ANSYS 11.0SP1 setup.
PROCESSOR_IDENTIFIER= Intel64 Family 6 Model 15 Stepping 7, GenuineIntel
C:>set PROCESSOR_IDENTIFIER=EM64T Intel64 Family 6 Model 15 Stepping 7, GenuineIntel
PROCESSOR_IDENTIFIER=EM64T Intel64 Family 6 Model 15 Stepping 7, GenuineIntel
You should also check the value given for PROCESSOR_INDENTIFIER under Control Panel > System Maintenance > System > Advanced Systems Settings >Environment Variables > System Variables. It should now be the same as the value that you have set above; modify itif it isn't.
Workbench should run after installing using the above procedure.
