Honored ContributorI had a similar problem involving PortManager.dll with DSP Builder 7.2 (no service packs) on a W2K machine.
When I tried compile in Signal Compiler I got: ============================= Pop-up window: MATLAB.exe - Entry Point Not Found The procedure entry point SymFromAddr could not be located in the dynamic link library dbghelp.dll ============================= signal compiler Messages: Info: Generating HDL Info: Analyzing Simulink model Matlab Error Java exception occurred: java.lang.UnsatisfiedLinkError: checkOut at com.altera.dspbuilder.portmanager.PortManager.checkOut(Native Method) at com.altera.dspbuilder.serialisation.ModelSerialiser.<init>(Unknown Source) at com.altera.dspbuilder.serialisation.ModelSerialiser.<init>(Unknown Source) at com.altera.dspbuilder.serialisation.ModelSerialiser.<init>(Unknown Source) Error: Error during compilation: Error: Error analyzing model see log for details. ============================ Matlab commando window: C:\altera\72\quartus\dsp_builder\bin\PortManager.dll: The specified procedure could not be found ============================ So I googled on SymFromAddr and dbghelp.dll and found http://msdn2.microsoft.com/en-us/library/ms679294.aspx DbgHelp Versions Versions 4.0 and 5.1 The following functions were added to DbgHelp versions 4.0 and 5.1. SymFromAddr So I noticed I had a rather old dbghelp.dll: C:\WINNT\system32>dir dbgh* 2003-06-19 13:05 163 088 dbghelp.dll I don't know how to check the actual version number, but I guess it's older than 4.0/5.1 I found http://www.microsoft.com/whdc/devtools/debugging/installx86.mspx downloaded and installed dbg_x86_6.5.3.8.exe and rebooted and then signal compiler worked :-)
