I'm developing a 64-bit USB application and cannot link to Performaxcom.dll

If you are trying to build 64-bit software, you will need to to use our 64-bit DLL, which you can find in the link below. The download is titled "SOFT-DLL-PMX-DLL-204" http://www.arcus-technology.com/support/downloads/download-info/usb-dll/ The DLL that comes with our standard USB driver, is 64-bit compatible, however it was built in a 32-bit environment. The DLL in the link above was built in a 64-bit system and should be used for building 64-bit software.

    I am having a similar issue, I am working in a 64bit environment but the included DLL is for 32bit. The above link appears broken, is there a new link?

    Thank you.

    Same problem but using an old Performax CD single axis driver. Would you mind showing the new link for the 64 bit DLL.

    thanks

    Hello again David,

    Hi Jamie, 

    It would depend on how you plan on using the .dlls. Generally speaking, you would copy "PerformaxCom.dll" and "SiUSBXp.dll" into your System32 Folder. That file location should look similar to C:\Windows\System32.

    Otherwise, you can include them in your project folder if writing your own software.

    Hi again David,

     

    I'm writing a Labview program using the old 1cd_labview sample as a template. It calls the dll.

    Hi Thomas,

    Got some spare time so I'm trying this one last time.

    Can you please tell me the exact sequence of events to install the USB driver for Windows 10, LabVIEW 2015 64-bit for one of the old Performax CD units ? I can detect it using the KOD package (console) but get a run time error when trying to write a command.

    cheers

    Hi again,

     

    I've tried that again. i.e putting both those dll files into Windows\System32 but i still get the same error.

    Is this the correct USB driver ? Looks to be a Windows standard driver ?

    I used the x64 bit installation from the KOD Labview source package on your News link

    Hello again, I've added another more modern controller (PMX-4EX-SA) and it appears to work fine with the installation. Is there any reason why the Performax CD would work differently ?

     

    thanks

    I've added another CD and it also appears not to work. Do these units work with the latest USB driver ? The 4ex00 works fine but the other 2 both give the errors shown above.

    Appears to me that the DLL doesnt work with the older CD units.
