I have the same issue as Biggle except that I use a 3405A picoscope and running on a Windows 7 64 bits computer:
run-time error '48'
Fine not found: ps3000a.dll
Before that I got this error:
Compile error: The code in this project must be updated for use on 64-bit systems
that I solved replacing all the "Declare" by "Declare PtrSafe".
I tried to give the absolute path to ps3000a.dll: C:\Windows\System32\ps3000a.dll
and moving the excel file to the picoscope installation path: C:\Program Files (x86)\Pico Technology\PicoScope6
with no success...
Could you please advise on this error?
I noticed also a PS3000a.dll file in the SDK directory, is that the same dll than the one from the installation directory?
