Hi Guys - its not only Win 7 64 bit but also Win 7 Ultimate 32 bit system that won't install FT232r USB UART drivers; I have tried all combinations of options available on FTDI site a number of times, including latest recommended methods and also older driver versions - nothing works as it should with all resulting in failures and I have simply given up having wasted several long days trying to resolve this issue!!
I get the big green ticks for the VCP and Com port drivers during installation but then when you try to update the actual drivers for each board in Device Manager by pointing to the folder where the driver files are supposedly installed they always fail!
My adapters include "genuine boards" from Sparkfun and separately from sainsmart (of which the latter I am not sure about how legit this company is as I have experienced a number of different problems in using this company - none of which were satisfactorily resolved by them - in fact the latest problem was simply ignored by them repeatedly asking the same questions despite me supplying all the required details/answers until after about 10 attempts I finally gave up in disgust???) so if the FTDI chip problem relates to use of the alleged fake FTDI chips then some "big companies" have some pretty big explaining to do! Seems like there is something very incidious going on here since so many people are having the same problems?

My only work-around at the moment is to not use this type of board for my XBEE / Uno projects, a real pain in the but and this has just forced me to order several (non-FTDI) boards that I know do work!
The other main problem with the FTDI Driver installation is that you are supposed to notate the path where the files are installed but the latest FTDI procedure produces an exe file for the driver installation and you have no way to identify where this finally installs the drivers as it is too quick to observe during running the exe installation file!
So if anyone can point me to where the FTDI drivers actually are installed in Win 7 Ultimate 32 bit during driver installation I will be very grateful. I rather suspect this issus is going to get much bigger before it is resolved! Please also note that these drivers are not visible or identifiable in Windows/System32/Drivers folder!!
Cheers Ian
