unit not opened error

Hello,

I am having trouble running the excel VBA script that came with the SDK. The function ps3000aOpenUnit always returns 0. I have 32 bit excel on a 64 bit system. I am running ps3000aV2. The dll's are in the syswow64 folder.

One theory, I do not have admin rights on my system. My user rights are Power User. Could this be limiting port access through the VBA script?

That would be the correct return code if the call is successful, PICO_STATUS_OK, any other value would indicate an error.

Hello,

I have the same error message "Unit not opened" when running ps2000a.xls
My configuration Picoscope 2205A, PicoSDK 10.6.10.22, Windows 7 / 64 bits, Excel 2007 / 32 bits
The 3 necessary dll's are in the right place and I have checked that Picoscope 6 is not running when running Excel macro.
Function ps2000aOpenUnit returns handle=0 and so the error message appears.
How to solve this problem ?

You need to use the 2000 drivers and excel example, not the 2000a ones, even though you have a 2205a device.

Thanks for useful reply. I had not noticed the need to use 2000 drivers instead of 2000a
I can now go further on.
