TC0832.dll not found in Win 7 64b.

Postby jd.phillips » Thu Sep 20, 2012 8:37 pm

I am trying to run PicoLog 5.22.6 with a TC08 serial datalogger, but every time I try to select the input channel I get the error message "Driver 'TC0832.dll' not found". I have tried running it as Administrator, installing using the XP compatability mode and several other things, but nothing seems to work. My system is a Windows 7 Pro 64b system and I am using the native COM port, not a USB adapter. Any suggestions?

Laptop or desktop ?

This error message can occur when there is insufficient power provided by the serial port and is a common issue with laptops.

RTS needs to be held at a positive voltage greater than >7V and DTR needs to be held at a negative voltage <-7V

It is a desktop with an Intel DH61BE motherboard and an i-5 CPU. Since my post I have tried this with a USB serial adapter and got the same results.

Yes. This worked fine on my old XP box, but I just replaced it with a new system.

What COM port number is it using, direct and via SUB ?

And what version of the dll do you have ?

Sorry for taking so long to get back to you. I have .dll version 2.7. The on-board COM is COM1 and the USB COM is COM5. I checked the voltage on the RTS and DTR lines and both are approximately -11V. I compared this to my old XP system and it is the same until the TC0832.dll driver is loaded then RTS changes to +11V. So it would seem that the driver needs to load to enable the proper voltage levels and since the driver will not load improper voltage can be ruled out. Is there any history of any issues running PicoLog in Windows 7 Pro 64b?

Can you navigate to
C:\Users\YourLoginName\AppData\Local\Pico Technology\42f31349-afb8-471d-8a4d4fb7672be39b

and delete all of the files in there before restarting PicoLog.

I'm experiencing the same problem on win7 64bit.

I tried the deleting the files in "C:\Users\MyLoginName\AppData\Local\Pico Technology\42f31349-afb8-471d-8a4d4fb7672be39b" but that didn't help.

Any other advice would be welcome.

Can you replace the existing dll with the attached one and retry.
