Hi MrChucky7
Not quite sure I understand what you mean with "my CPU give me an error message"... I guess you have to mean that Windows XP as an operative system tells you it can't find the Setup file.
And what do you mean with "I open up (All Files) there is no setup files" ?
I checked on Tascam internet site and found both Firmware and Drivers there. I tested to download both of them to take a look.
https://tascam.com/downloads/tascam/309/FW1804_Win_1.80.zip
Inside this zip-file there is an EXE-file that are used to install the Drivers that installs into Windows system.
https://tascam.com/downloads/tascam/309/fw1804_firmware_updater_183_49_Win.exe
This is an EXE-file used to install the Firmware into the FW-1082 itself. But it's only an update and I'm not sure if you have to have an earlier version installed first for this one to install properly. I unpacked this exe-file with 7-Zip and inside there is two different BIN-files, one txt-file and an Fw1804Updater.exe
It should work to start the original exe-file. But maybe it works better to extract that exe-file and start from the exe-file inside the first exe-file. It's not always that the install-file is called "Install" or "Setup" but simply the name of the program with .exe at the end.
If Windows already have detected FW-1082 the instalment SHOULD work without problem. But there could also be some problem with Windows Installer itself, and that there are some missing files in the Windows system.
From the instalment PDF:
"Make all (computer, audio and MIDI) connections to theFW-1804 with the power turned off."
"Do not connect the FW-1804 to the computer until you have installed the software."

Hope some of this can help you a bit on the way. XP is pretty old and more unstable than later versions, but since Tascam probably doesn't support this older hardware in newer versions of Windows, I understand why you have XP installed. Lots of people does that, since older hardware AND software won't work in newer versions of Windows.
