I got a CS320 serial number FF3371 and installed the supplied DVD with a success message. Connecting the USB cable no driver is found. Windows "Geraetemanager" shows "Cleverscope CS328 USB scope" with a yellow warning sign. This does not vanish when searching for a driver on the dvd. So which driver should I use here on Windows 7 64bit?

I did download "Control Driver Installer 2400". The install.msi went through, but the yellow warning sign of the USB driver did not disappear. I then gave the folder where the driver seems to be. But unfortunately at the end of the process I am getting a message "Fehler beim Installieren der Treibersoftware für das Gerät". "digitale Signatur kann nicht überprüft werden". "Code 52". Search for driver software on site of supplier is given as a hint. See pictures. What next should I do to be able using this at last?

Yes, you can use the CS320 with Win 7 or Win 10 x64. However you should not use the DVD for install. This was made before Win 7 x64 was invented, and the driver is not signed, and not x64 bit compatible. It is much better to go to our downloads section, and download the latest installer. This includes drivers that are compatible, and signed. Here is a link to the downloads: https://cleverscope.com/resources/, click on the software drop down, and install either x32 or x64 bit versions of the application. The x64 bit version of the application is the latest, but it is much larger. You will currently need the x32 bit version to calibrate the CS320 (the x64 bit version does calibrate the CS328A and the CS448/CS548).

When you install make sure you tick the 'Install Classic Cleverscope CS328 Driver' option.

Using the latest install of the web is also better for making sure you are getting any additional features that have been included since the DVD was made.

Good luck!

I now used this zip: https://www.cleverscope.com/files/Cscope%20Installation%20Disk%20469994.zip and install.msi. There came up an error 1311, source file not found. But data.cab was there and accessible. Second time this worked. But the yellow sign indicating USB driver problem still is there. When deleting the driver and reinstall the same problem as above is coming up, "Code 52". What else could be done here?

Hello Matt,
It is very important to follow the instructions which say "Extract folder in zip to your hard drive and run setup.exe". Follow the instructions in 'Cleverscope CS448 - CS328A Installation.pdf' which is inside the zip.

Running just the install.msi, which is only a part of the total install will not work.
Please make sure you copy the contents of the zip onto your hard drive. Do not run the installer from inside the zip.

Run setup.exe.

Make sure you tick the 'Install Classic Cleverscope CS328 Driver' option.

Hopefully the install will still work. Good luck.

Hello Bart,
running setup.exe works. I checked which driver files are used and deleted ftdibus.sys, ftbusui.dll, ftd2xx.dll, FTLang.dll from system32 and ftd2xx.dll from syswow64. Reboot. I deinstalled all I could. Then I installed only the driver using setup.exe. This seemed to be successful because no yellow sign at first when connecting the USB cable. But there came up a message "has not been installed". Next time when connecting the yellow sign reappeared. The driver tells: "digital signature cannot be checked (Code 52)". FTDI 2.12.28 "not digital signed".

Hello Bart,
the problem vanished after this update for Win 7 has been used: 2019-09 Sicherheitsupdate für Windows 7 für x64-basierte Systeme (KB4474419). Thanks to Roger for this hint !

Hi Matt,
Great to hear!
The problem for the everyone else, is that our .cat file, which signs the .inf USB driver file, uses SHA-256. Windows 7 only supports SHA-256 with SP2, or the update that Matt used. Earlier versions of Win 7 thought the .cat file was invalid, and refused to install the driver.
